Hello. I have a question about a
rosemary plant. We transplanted a small rosemary plant
to the front of our yard last fall. It has grown a
bit, to over two feet tall. Today I noticed that the
tops of its branches are curling down into a 90 degree
angle. Is this normal growth, or a problem? Could it
be due to over-watering or crowded roots? I have never
trimmed the plant, should I start to do so now, at the
start of the spring? This is a very special plant to
us, planted to commemorate the passing of our dog, who
loved to walk through rosemary bushes. Any help you
could offer would be greatly appreciated. Thanks, ER
After you wrote I noticed
some of the new growth on my own plant was doing the
same thing. I also noticed that these branches were
probably getting knocked against the barbeque grill by
the wind. Perhaps yours are also getting a bit of
abuse by the weather. I don't think it indicates any
big problems but you certainly couldn't go wrong by
giving the plant a trim.
Hello, I began growing a small
rosemary plant at the end of the summer. It lives on
the front porch in a medium sized pot (about 10"), and
gets good sunlight. I have used a few sprigs here and
there, but it is not growing back and is beginning to
look a little thin. What can I do to help it grow
back? Thanks! SRS
You don't say where you
live so it could be that your plant has gone into a
slow growing phase because the weather is cool or
cold. If your temperatures are low I suspect your
plant will resume growing again once it warms up a
bit. If you are in a warm climate, you might consider
adding a bit of lime to the soil or giving the plant a
light dose of fertilizer. Pay attention to
watering--not too much but not too little either. Find
more tips below.
We have several rosemary
planted on the north side of the house. We are in
southwest Florida in an area that was formerly swamp
type land that was filled with who knows what.
Although they seem to be growing, most of the plants
are turning gray. They were green and healthy when
transplanted. We mulched with grass clippings after
transplanting. Any clue as to what might be the cause?
Rosemary is often
described as having gray-green needles so it might
just be a natural state developing as it matures. Look
closely, however, because if you see a sort of
talc-like substance on the leaves, it might be powdery
I live in NYC and want to
know if I should keep rosemary inside under a grow
light throughout the summer (it would get 6-7 hours
direct sunlight) but I'm afraid of it getting watered
too much by summer thunderstorms. Also how should I
take care of it for the winter (and how to move it
inside if it should be brought outside). BH
Your rosemary would
probably be happier outdoors in natural light. You
don't have to worry about too much water as long as
the pot it is in has a drainage hole in the bottom.
Good drainage is very important to rosemary. The plant
can handle cold temperatures but if it gets down into
the 20's (F) you would want to protect it by bringing
it indoors to a sunny window or moving it close to a
building out of the wind.
I have a small rosemary plant
in a pot that I want to use as a kitchen herb. It is in
it’s second year (quite a trick as I live in Ontario and
winters are short on daylight). It is starting to sprout
flowers. Do I trim them off to keep the herb plant as a
herb or do I just let them bloom? Will it affect flavour
or growth? PC
Sounds like you have a happy
little rosemary plant. The flowers are just a natural
part of growth. You don't need to trim them off and they
won't change the flavor.
I have 2 slightly different
looking rosemary plants. Both are very healthy and
growing like weeds, but neither has any scent, even when
rolled in my fingers. What's up with that? Thanks for
your help! LM
It may be that your
plants are growing so fast that they don't have the
energy to generate essential oils. If you are using a
fertilizer, stop and try allowing more time between waterings.
Hi, I have a rosemary plant that
I've had for about 3 years on my kitchen window sill. It
was doing great, but getting little bushy, so I trimmed
it a little bit. This was about a year ago. Since then
it has been in continuous bloom and has not grown at
all. I've looked on the internet, but everyone seems to
have the opposite problem! I don't want to use any
leaves from it, since it is not growing. Any ideas to
get it growing again? Thanks, BD
Sometimes plants throw out
flowers when they are in trouble. Since yours is an
indoor plant, I wonder if you might be watering it too
much. Rosemary hates wet feet. Light may be another
issue. Perhaps you could move it to a window where it
gets more sun.
Hi, I have a Rosemary plant that
will be in its second season now. Is there any change in
quality as a herb for cooking that takes place with
Rosemary as the plant gets older? I very much would like
to keep the same plant for a few years but want to make
sure that the Rosemary does not reduce in strength and
flavor, or get bitter, as the plant gets older. Also,
once the plant is in bloom, is there any noticeable
change in the flavor of the Rosemary? Great Web site!
Rosemary plants age quite
well. I don't think you will notice any change as it
gets older or when it blooms.
Hi! I have a large Rosemary plant
in our yard and it never blooms. We live in AZ. and
their are plenty of Rosemary plants every-where, all of
the others bloom with beautiful Purple and ours never
bloom. The scent is also much stronger than the others.
Do you have an answer? Thank You. JP
I can't really come up with
a good answer except to inquire about your pruning
habits. It could be that you are pruning your plant at
the wrong time of year, in effect cutting off the
forming blooms. The best time to do any major pruning to
rosemary is after it has flowered. Most rosemary
varieties bloom spring to summer but given your
location, I suppose this would be considered spring.
Hi. I had a nice rosemary plant
growing over the summer, brought it in the house as
winter approached and it died in the house. I've been
cooking with the dried leaves off the dead plant as I
would normal dried rosemary. Is it bad to eat the
dead leaves or is it basically the same as normal dried
herbs? Thanks BD
Considering that we
basically kill the branch that we snip from the plant, I
think you're right that it is like other dried herbs.
I have a rosemary bush on a
barrier island off the coast of NC. It’s about 5 ft
tall, however ½ of it is dead or has no leaves and is
brown. I have never pruned it . It is in sand. An ole
farmer told me to prune it back to the ground. Is he
I don't know if you have to
prune it all back. I would start with just pruning out
the dead branches.
I live in Eastern Pennsylvania. My
established in-ground Rosemary crop looks brown and dead
at the bottom of the plants, like it is dead from lack
of water. But many of the branches have green and alive
top section (maybe 3 inches of the top) are alive while
rest of branch looks brown and dead. We have had very
bad summer weather. First, two months of extreme heat
and drought and then a month of extreme record setting
rain. Do you think all these plants are dead from a
disease/blight, or are suffering from weather? Is there
anyway to save them if only the tops remain green with
whole sections are brown and dead-looking? I have
managed to winter over these plants for three or four
years now, even in zone 6. This is very devastating.
Please help. DDB
Rosemary is a rugged plant
and it sounds like yours is bouncing back after a rough
summer. I would leave it be for now, any sort of
trimming may stimulate tender growth that would be at
risk in the cold, and then evaluate the plants in the
I have just bought a house
surrounded by established beds with a variety of local
plants [Houston, TX] I was delighted to find a rosemary
bush tucked in with all the other stuff. My teen has
already used it in one dish [lamb chops] with satisfying
results. Tonight I went to cut some for the pork chops,
and notice a sticky feel to my fingers, and pine-like
smell. Seems I have the “pine-scented” variety. However,
upon closer inspection, I find the leaves appear to be
‘dusted’ with a whitish or whitish-yellow substance. It
does not brush off or scrape off easily. Is this the
mildew I have read about on the web? Or perhaps
spider-mites? Or something else I don’t know about. My
plant knowledge is limited and my reputation with plants
in general is dismal. What do you think it is? Will it
hurt the plant...or me if I eat the rosemary? How to get
rid of it? Thank you very much, AM
Rosemary generally has
that pine scent and is somewhat sticky, however, the
condition you describe is most likely powdery mildew. It
is a fungal disease caused by lack of air circulation
and/or hot, dry weather. The
Colorado State University Extension Office provides a
good online article about the subject. Personally, I
don't think I would eat the rosemary until the condition
has cleared up.
Do I need to chop or at least cut
up my fresh rosemary before I measure it for a recipe?
Most recipes will specify
how the rosemary should be prepared. If a recipe calls
for a sprig, you don't need to chop it, but if it calls
for, say "1 tablespoon fresh," they would mean the
leaves should be removed from the stems and chopped or
A few years ago my room mate grew
a rosemary plant from seed. I am not sure which breed.
When he moved he left it with me. I planted it in the
ground last spring. It seems to be doing well despite
the incident with with a lawnmower. This spring I
noticed that some of the leaves are growing bigger and
turning red and brown on the ends. They don't seem dry
and smell normal. Is this a problem? Does it have
anything to do with it never blooming? --Pass some love
will tell, but I suspect the lawnmower incident took off
the forming blooms and resulted in a bit of damage to
the remaining branches. The leaves may be growing larger
this year since the plant has become better established
in its new spot.
Hi there. I had a beautiful
rosemary bush until I cut it back. It has been a very
bad winter this year and it was looking really bad. So,
I cut it thinking I was helping it, but I may have
killed it. Do you think there is a chance it will
survive? I have a very large and developed herb garden
and would hate to have to replace it with a young plant.
I think it will come around,
especially since it is an established plant.
I have a rosemary Christmas tree
that my husband bought me but on the back of the
information card reads for decoration only: do not
consume. Is this true? TL
Your plant was probably
grown with chemicals to stimulate growth and prevent
pests so it is considered an ornamental rather than
I have a large 4' plus tall
rosemary bush which is planted in my garden. It is
starting to split in the middle and lay down and a few
of the branches are
yellowing. Can I transplant the bush, split and break
into more than one plant or would doing so kill it. What
could be causing the yellowing? I live in
southeastern North Carolina so weather is not a factor.
I had a similar situation
when snow broke my rosemary bush right in half. My
recommendation is to look and see where the break is and
trim off the part that is only hanging on to the trunk.
You won't be able to salvage the broken part just
because that isn't how this plant is propagated. The
yellowing is likely due to the fact that those branches
are no longer attached to the plant. Once you have
established which part of the plant is still attached to
the rootball, it shouldn't be any problem to transplant
that part. My own rosemary is thriving now.
I live in Las Vegas and my
rosemary bushes have little clumps of white foamy stuff
all over them and they are turning brown right in the
center of the plant, both of them. What's wrong with
them and is this something that might spread to the rest
of my plants? JG
Sounds like spittlebugs,
which don't generally hurt plants although they can. Try
giving your plants a strong spray of water to wash them
I live in Reno. NV (zone 6-7).
I have a 4ft tall brick planter that I have been trying
to grow trailing rosemary in. SOME years the plants over
winter, but, usually I have to replant some if not all
of the plants. I was wondering if I twined a cable soil
heater or heat tape around the plants when I replant if
that would possibly protect them when the temperatures
occasionally dip to 5 degrees or so? If you don't think
so, can I train a cold hardy upright type of rosemary
(Arp or Madeline Hill ,both zone 5-6) to be more
prostate by pruning somehow?
Thank you for any help you can give me!!
so often happens with this Q&A, I have learned something
new. I didn't know these cable soil heaters even
existed. I can't imagine why your idea wouldn't work.
You might ask more questions about using them from
whomever you buy it since it seems like a bad idea to
use electricity around water.
I have a potted rosemary that
had grown fantastically over the summer. I live in the
southern most Lancaster PA, and as the fall settled in
we brought the planter in and placed it in the southern
exposure window and all of the leaves (needles) have
dried and fell of and the stems have died out. I have
harvested the herb and moved the plant to the garage to
see how it winters. Do you have any thoughts? JB
I think you're probably
going to need a new plant. Rosemary has a hard time
recovering from drying out as you describe. You are
right to give it a chance and the garage is a good spot,
especially if there is a window. Next year, you might
want to try taking the pot from the outdoors right into
the garage and it will likely fair better (unless, like
I always do, you forget to water it!).
I live in the northern Chihuahuan desert of New Mexico. It is not like Arizona
or California because the altitude is higher (4000 feet)
so it gets cold, below freezing, in the winter. I have a
beautiful trailing rosemary in a pot in my courtyard. In
the summer I water it when it is completely dry as
recommended and it does fine. Does the same hold true in
the winter? Thank you. DD
Plants tend to dry out a bit
quicker in the cold so you should follow your regular
watering pattern, but maybe just keep a closer eye on
On the soil of my rosemary plant,
there is some white stuff around the edges of the pot, I
water every other day, what is the white stuff? Thanks,
Most likely it is a calcium
build-up or some sort of residue left from the minerals
in the water.
I have access to rosemary that
grows along a busy 4 lane road. I make a meat rub with
rosemary and want to use this rosemary. When I picked
the rosemary my fingers were not only sticky (common)
but were very black with what I assume is road grime.
How do I wash this rosemary so it is safe to eat? Thanks
I say don't eat it. These
plants have been exposed to engine exhaust for their
entire lifespan. That can't be a good thing to eat.
I used to order a dish call
"Rosemary Chicken" in a restaurant in Dillon, CO. They
have since discontinued making it and I asked them how
was it made. They told me a few ingredients - rosemary
herb and whipped cream and poured over ravioli filled
with chicken. The color of the sauce or gravy was olive
green. It was delicious. I am not a great cook but would
you have any idea how to make it? It was some what
sweet. Thank you for listening. CA
That does sound good. I
would start by trying a simple reduction of
rosemary-infused cream. This is accomplished by bringing
the heavy cream to a full boil, add a few sprigs of
rosemary and continue boiling until there is only half
as much cream as you started with. Strain out the
rosemary then season with salt and white pepper.
I'm not sure if this would make it the olive green you
describe, but I'll bet you would get a nice flavor.
Hi, I purchased several rosemary
plants this past summer. Two I kept in the house by the
window and they produce light and tender needles. The
outside bush has become large and the needles are
broader and much larger. It looks very healthy but not
as nice to eat. Perhaps they are different
varieties....do you think both are edible? I wonder if I
should just let the larger one grow into an evergreen as
that is the appearance it has. I love cooking with this
wonderful herb and appreciate your website, it is very
helpful! Regards, HS
There are many different
varieties of rosemary and as long as you are certain the
one outdoors is actually rosemary, there's no reason not
eat it (except that it doesn't taste as good). They do
make nice shrubs. You might also enjoy using it for the
flavor and aroma by throwing a few of the branches into
the fire next time you barbeque.
I bought a rosemary plant from
Home Depot about 6 months ago. It sits on the back porch
and gets approximately 6 hours of direct sun. About a
month after I got it half of it leaned over and died.
The small 6 inch plant that is left has never grown any
more. It looks very healthy and green with great aroma
and I have pulled off a couple of the leaves for cooking
and it is just getting smaller. What would you suggest?
Sounds like maybe a stem got
broken off of the side that died. For the part that
remains, make sure you aren't overwatering and give it a
little more time. It sounds like it's okay, but you
might give it just a light dose of a natural seaweed
fertilizer to invigorate it.
I live in Miami and I've noticed
when I pull the leaves off the stem of my rosemary plant
to use it the leaves don't come off easily and the plant
it a bit sticky. I've rinsed it off and used it but is
this safe? Do you think it is because of the heat? Thank
Just from curiosity I went
out and snipped rosemary from my own garden. After
stripping the leaves, my hands did seem a bit sticky.
The leaves came off easily, however, it was tender new
growth. Perhaps yours are resisting because it is from
an older part of the plant?
Hi - I've been reading your Q&A
page this evening and you certainly are a wealth of
knowledge! I didn't see anything that pertained to my
situation so I'll ask directly: I live in central Texas
(Austin), which seems to be a great climate for
rosemary. A friend is moving and offered to let me
have/transplant her rosemary bush, which I'd love to do.
However, you say that spring and fall are the best times
to do this, and now it's already in the 80-90 degree
range here (Fahrenheit). Is it unwise to transplant in
this weather? And do those times also apply to planting
rosemary plants purchased, say, from a nursery? Thanks!!
You can transplant at any
time of the year, but the heat will be added stress so
you'll want to baby your plant along for awhile. Make
sure the soil it goes into is high quality, maybe add a
bit of compost if you're putting it into the ground, and
provide plenty of water as needed. Do keep in mind that
rosemary doesn't tolerate "wet feet" so don't overdo the

I think I would start with
about one teaspoon dried rosemary for this switch and
then taste it to see if that is enough.
Hi - I brought my 2 rosemary
plants inside to winter a couple of months ago. We live
in Minnesota. Usually I just cut down my rosemary in my
herb garden in late fall and just start fresh and
buy/enjoy a big plant throughout the summer and fall. I
thought I would try potting them this year and try and
winter them. Sunny southern exposure near our front
door. They appear to be doing fine however I noticed
today that there are tiny tiny black bugs all over one
of the plants and now on our curtains. I assume they are
aphids. There are no other house plants. Is there anyway
I can treat them? They are tiny! Thanks! HC
If they are indeed aphids
you should be able to wash them away with a strong spray
of water. Since it's probably too cold outside perhaps
you could accomplish this in the bathtub.
Hello, I'm hoping you can
suggest a rosemary that I can perennialize in my zone 6a
garden. I have a few large cold frames and have found
that many plants and herbs survive very well in these
throughout the cold months of the year. But there are
constraints. Space in the cold frames is at a premium,
and nothing that grows too tall is suitable. And I want
a good culinary variety, not one that just looks nice.
So, is there a savory and prostrate variety of rosemary
that doesn't grow too wide or too tall? I got an unknown
variety of rosemary once that in retrospect seems
perfect, but that was before I had cold frames, and it
died in its first winter. Thanks for any suggestions. KH
Take a look at a variety
Territorial Seeds says it will survive to zone 5
with minimal protection. It gets to be about 4 feet

Good morning, I am trying
to determine how large (width and depth) of a hole I
should dig to give my 2 yr old potted rosemary bushes
roots plenty of room to grow in the future when planted
in our landscape. In what direction does the root system
of a rosemary bush grow in nature? Down? Straight out
(horizontal)? All over? Do the roots extend past the
outer-most branches? And in what proportion is the root
system to the plant above the ground? Right now the
plants are about 18-24” tall and ~ 18” across planted in
8 gal pots. I live in zone 8b (Austin, TX) with hard
clay soil so I know I need to break up the soil really
well, amend with compost and provide good drainage. Just
want to know which direction should I should focus my
digging? Down or out? DM
I would go both ways digging
a hole that is about twice as wide and deep as the pot
that the rosemary is currently in.
My rosemary has scale. Can I spray
it with an oil spray before bringing it in for the
winter? I don’t need to use it for cooking until I get
rid of the scale anyway so the oil will not be a problem
in that respect. Thank you so much! AW
I can't think of any reason
why you couldn't spray the plant. Just make sure you are
using the proper spray for the pest you have and that it
is safe for food plants.
Hi dear, my 10 years old rosemary
bushes has light green sorts. I spray for bugs, Ortho
product and is not getting better. One bush after the
vibrant color green the leaves started to dry and the
whole tree dry to death. Please help me how stop this
madness. Thank you CM
I doubt that bugs are your
problem. It's sounds more like a deficiency or a
disease. The best thing you can do it snip a good-sized
sample and take it to a local nursery or greenhouse to
see if they can help you remedy the situation.
I live in Las Vegas, NV. My
landscape architect just planted creeping rosemary in
our new front yard. I’m wondering if creeping rosemary
is safe to use in cooking, or if it’s just for “looks.”
Thank you. LP
Creeping, or prostrate,
rosemary is indeed still culinary rosemary. The question
here is how yours were grown. The nursery or supplier
may have used chemicals to produce hardy,
landscape-worthy plants so you should check the origin.
Hi, I have an 6-7ft rosemary plant
that has been in the same place for about 12 years. This
year some of the branches have a brown crusty sort of
stuff on them and a good part of the lowest section of
them have turned gray and I believe are dying. What is
the brown stuff, does the gray branches mean it is dying
and how much should I cut back? I have read not to cut
more than one third but there is more than that on the
plant. This is the first time I have had any issue with
the plant. It is beside an lilac tree and a sage bush,
which neither of them as shown any sign of problems.
Thank you for your time to answer this issue. CO
It's hard to say what the
problem or problems might be without seeing the damage.
It might be a good idea to take a sample branch to your
local garden center to see if they can help you.
When visiting my daughter in
Sacramento, California, I see such beautiful rosemary
bushes. I would like to find a perennial rosemary that
would stand the cold of zone 5 in Chautauqua County,

You may be out of range
for the rosemary plant of your dreams. The folks at the
National Arboretum have put together
a list of winter hardy varieties along with tips to
help plants through the winter. One alternative would be
put get a large pot on wheels that you could have a nice
rosemary plant outdoors in the summer and then take it
inside during the winter.
HI, My Rosemary is about 5-6
years old at least, 4 feet tall, and has been
flourishing every year. I just went out to cut some
branches to bring indoors and noticed that there were a
number of dead branches and the tip of every branch had
needles that were a darker brown and dying. I cut off
each tip, but some of the needles further down were also
a dark brown. I brought in some of the dead branches and
may use them in my smoker or BarBQ Grill. Any idea on
what is causing the branch tips to turn brown and the
branches to die? We did have a cold winter this year,
but not a lot of rain or snow. Thanks, CCS
Your description fits what
happened to my rosemary this winter too. I noticed some
branches were dead because they had broken off under the
weight of snow. In addition to the stress of the cold,
your plant could be a little dehydrated as well as wind
whipped. If you aren't getting much rain you might want
to give it a drink but it should be okay.
I have had great trouble recently
acquiring Rosemary. Any suggestions why this is and is
there a substitute? RI
I can't imagine why you
would have trouble getting your hands on rosemary. It's
been a tough winter but rosemary is a tough plant. In a
pinch, you might use lavender as a substitute. They are
similar in flavor.
Hi, We live in Northern
California and have four true seasons winter snow etc.
and have creeping rosemary in our garden area. These
have been in the ground for many years and have been
thriving. They are actually quite large. However this
winter it appears we have lost 98% of the plants. They
just began to turn and drop all the leaves. Should I cut
them back and hope they will regrow or leave the
branches in hopes that they will rebloom? Thanks for
time regarding this matter. SB
I've been hearing many
people say they lost their rosemary to this crazy
winter. I suggest you give it a bit more time to see if
they will start putting out green leaves again. Once
they do, if they do, you will see what is dead and can
prune that out.
When I was in Nev. this past
summer I saw spreading rosemary used as ground cover, it
looked beautiful. I live in central Florida and have an
up right rosemary in the garden. Will the
spreading/trailing rosemary grow here? So far I have had
no luck finding it at any local stores. BD
The variety you seek is
known as "prostrate" and should do well in your area.
You might look for nurseries that specialize in rock
garden plants. I did find it for sale as a plant only in
Territorial Seed catalog.
I planted rosemary
approximately 6-8 months ago. I thought by now it would
have grown outward to each side, as I've seen most
rosemary bushes. Instead, all my plants have grown a
couple inches upward. What did I do incorrectly or did I
plant the wrong kind??? Thanks GG
It is a plant's natural
inclination to grow up rather than out. To encourage a
plant to be bushy instead of tall we can snip from the
uppermost growth. This causes the plant to send out
shoots from the side as well.
Greetings: I love the taste of
Rosemary and I have a habit of grabbing a piece if I'm
walking down the street and a business might have a bush
growing. But sometimes I've noticed that it'll make my
throat burn and I wondered if there was any harm eating
Rosemary without washing it off? DL
It is a bad idea to eat any
plant if you don't know how it grown or if it is not
grown as a food. Landscape plantings are often treated
with pesticides and fertilizers to maintain a lush
My recipe calls for one bunch of
rosemary. It's 2 degrees outside. All I have in the
house is ground rosemary. Can you help with a
One bunch of rosemary is a
large quantity. I'm guessing it would be removed at the
end of cooking. To flavor the recipe with ground
rosemary, you might start with a half teaspoon or so and
taste to see if you need to make adjustments.
Hi & thanks for having such an
awesome resource! The people that maintain our lawn were
cleaning out our flowerbeds thinking they were doing a
good thing. Turns out they cut my wife’s rosemary bushes
down (apparently thinking they were weeds?) at the base.
The plants were about 3 feet tall and ½-3/4” in diameter
at the base. Are these plants pretty much toast or is
rosemary hearty enough to actually grow back from such a
calamity? We live in Charlotte, NC – a very rosemary
friendly place, climate-wise. Thanks in advance! CH
Oh dear. Given your
location, I would bet that they will come back. It
shouldn't take too long to see if new growth occurs. I
am quite curious, however, so I hope you'll let us know
Hi, I have a rosemary plant
approximately 6 months old and I've noticed that one of
the main branches and its subsequent branches appeared
broken open in areas revealing patches of small bumps. I
have pruned the offending branch, but was wondering what
could have caused this to happen. Thanks. JT
It's nearly impossible to
say without actually having seen it but perhaps there
was winter/spring-related damage from temperature
fluctuation or some other bark injury before you got it.
Hello! I’ve had an established
rosemary plant outside my home for at least three years.
A few weeks ago I noticed small white hard lumps on it,
each about the size of a half grain of rice… when I
pulled one off, it appeared to “bleed” and even smeared
a “blood colored” substance on the paper. I waited and
did not see a bug or anything emerge from the small
lump… what am I looking at and do I have to dig out my
rosemary to save my other plants (tomato, basil, sage
etc). Thanks! VF
I want to say that it might
be an insect called "scale" but I'm not aware of them
bleeding. Scale usually appear on the bark of the main
stem and can sometimes be eradicated by wiping them off
with cotton balls soaked in rubbing alcohol. Please do
look into this insect further before taking any action.
Hi there- We planted two rosemary
bushes on the ground that we bought from the nursery
about a month ago. Both bushes don’t look too good as
their leaves are curled, look dull, and not so green
(small specs of yellow). The bottom branches have dried
out and so were the leaves on it. Before planting, we
tested our drainage and water seems to drain ok. We’ve
only been watering twice at most three times a week at
this time. All the other plants that we planted next to
it are doing very well. The rosemary does not seem to
have any sort of infestation at all. We also don’t
notice spurt of new growth. Any idea what condition our
rosemary might be in? Thanks for your help!! PD
Your plants may just be
suffering a bit of transplant shock but I'm also
concerned about root rot or crown rot. Rosemary is
susceptible to these fungal conditions. Gently move the
soil away from the stem at ground level and see if it
looks healthy or sort of blackish. You might also cut
back on the watering a bit. Check about three inches
down into the soil to see if it really needs water.
I think my rosemary plant has
spittle bugs. What would you suggest to get rid of the
spittle bugs and white foam? After getting rid of the
bugs and foam, would the rosemary be safe to use in
cooking, or would the spittle bug eggs still be likely
to be in/on the plant, and could they become like a
parasite for humans? Thanks, D.
Spittle bugs are mostly
harmless. You could try just washing them off the plant
with a strong stream of water. I wouldn't be worried
about the rosemary being safe but if it makes you more
comfortable you could just wash it well before using.
My rosemary plant (potted) has
white sap oozing out of it, close to the tips of the
sprigs. What is it, and is it harmful to the plant or to
people? The weather has been damp. D
My first question is if the
sap is actually coming from the plant or could it be the
result of a pest like the spittle bug? They leave a sort
of foam behind them as they feed.
I am starting the South Beach Diet
and one of the recipes calls for both Rosemary leaves
and Rosemary sprigs. I have tried to find pictures of
both to distinguish the difference, but have so far been
unsuccessful. Can you please tell me the difference
between the 2?
The leaves can be stripped
from the stems by holding the tip in your fingers and
pulling down gently in the opposite direction of which
they have grown. A sprig is just the leaves still
attached to the stem.
Hi, I planted some rosemary
seeds in a small container last spring. They germinated
very fast and within the year, I had a nice long stalk.
About 5-6" tall. I transplanted it this spring and it
doesn't seem to be growing at all. Rather, it looks
dried out (not sure if its died or not). It gets full
sun, I water it
every morning as the soil is dry (I live Tucson).
Please advise! Thank you D
Congratulations on growing
rosemary from seed. It isn't easy to do! Sounds like
maybe it didn't take well to the transplanting, however.
Watering it everyday may be a problem, rosemary doesn't
like wet feet. Dig into a the soil a few inches and see
if it is dry beneath the surface as well.
I have a rosemary plant several
years old in a huge wooden planter. It stays in bloom
all year long. So much blooms that I can't really cook
with it. I want the herb to cook with not for flowers. I
live in the Pacific Northwest also it doesn't get a lot
of water. It rains a lot here and I only water it in the
warmest part of the summer (hi 60's) If I water it more
will it quit blooming? HB
I haven't run across this
problem before with rosemary. Sometimes blooming can
indicate a plant is in distress. It might be a good idea
to refresh the soil in the planter. Over the years the
nutrients wash away. It wouldn't hurt to water more as
long as there is proper drainage and you let it dry out.
Plants in pots need more water than those in the ground.
I live in central Alabama and have
two rosemary shrubs that grow lavishly but have never
produced blooms. I have to trim them every year because
they cover our walkway. What am I doing wrong? Thanks!
You may be trimming away
those nice blooms. If you can, leave the plant alone for
a year or more and see when, and if, it blooms. Rosemary
is known to bloom at different times of year. Also,
don't fertilize the plants as this encourages foliar
growth rather than flowers.
Hello, My daughter lives in London
and is trying to grow herbs in her apartment. She has
basil which is doing fine and Rosemary which has
developed leaf curl. I suggested she look for some type
of critter under the leaves such as spider mites, aphids
etc. but is there some type of virus/fungus that might
cause this as well? What other conditions might cause
this to happen? Thank you for any possible causes to
this problem. CG
As always, it's tough to
identify a problem without seeing the damage. You are
probably on the right track with a critter infestation
but rosemary is susceptible to overwatering problems as
well. These would include root rot and crown rot. Make
sure the plant has good drainage and good air
circulation and let the top two or three inches of soil
dry out between waterings.
I live in Memphis, TN and have a
very large rosemary plant. The lower limbs are thick and
it has spread all over my vegetable garden. Can I move
this plant? Can I cut it in half and move the halves? MW
You can certainly move the
plant but dividing it is not a good idea. Because
rosemary grows from a single stem the operation would
probably kill it.
I have 2 rosemary bushes (About 2
feet tall) that my previous neighbor planted about 18"
apart. I know from lots of reading that this is entirely
too close. I would like to move them. I know they do not
take transplanting well so I want to do this right. I
found lots of information on how to transplant my bushes
but not a whole lot on when. I live in North Carolina
and I would like to know when is the best time of the
year to move them. Any help would be great. They are
wonderful bushes. Clueless in Carolina
I have a lot of Rosemary and want to make fresh
wreaths—is it necessary to buy an Oasis for the
wreath, or can I just make it with a wire wreath
base? Also, what is the best way to make the wreath?
This is something I
haven't done before so I wanted to point you to a good
website for help. Unfortunately, there are so many
different ideas that I think you should look around for
yourself. Just try a Google
search with the words "make a rosemary wreath."
You'll be amazed at all the clever ideas.
I put in a rosemary bush this
spring and it has loved our sandy soil. I am now
worrying about whether it will survive the coming
winter. Should I leave the plant outside or would it be
better to put it in a pot inside our home and grow it
that way? What would you recommend as potting soil if I
do put it in a pot? DY
Rosemary can take
temperatures to around 25 degrees (F). It doesn't like
replanting so if you must do so, be gentle. An
all-purpose potting soil should work, just make sure it
has good drainage. See the entry titled "Gardener's
Hint: Rosemary Basics" on the
More Tips and Hints Page for more information on
growing it indoors.
We live in the desert of Southern
California and the property we live on has a number of
Rosemary bushes. I'm not sure of their age, but they are
approx. 3 1/2 feet tall by 4-6ft around. Most of them
appear to be dying from the inside out and I don't know
what to do. They do get regular water as they're on a
system, so I know they're not neglected in that way. The
new young volunteers that have sprouted around these
older ones look very healthy. Should I cut them back? Is
it a lost cause? I hate to see them go... we and the
bees love them. DR
We have clay soil here in
southern France and my thyme and lavender are both doing
very well... however my 7 rosemary bushes which started
out very well (planted from young plants before the
thyme and lavender, but in same soil, over a year ago)
have been going yellow to brown to dead branch by
branch, plant by plant. I am at a loss....
Help? Please and thank you. CN
I'll answer these questions
together since it sounds like drainage may be the
problem in both cases. This in turn could lead to root
rot. I encourage both of you to research the topic a bit
more to see if you can make a positive identification of
the problem. Meanwhile, back off on the watering a bit
and go ahead and trim away any dead branches as this
will help circulate the air around the plants better.
I bought a rosemary Christmas
tree about a year and 4 months ago. I transplanted the
plant to a larger pot and it grew for me for an entire
year outside here in the hot, humid climate of Houston,
Texas. It had made it through another winter and seemed
to be doing fine. Now, suddenly the plant seems to be
drying out from the inside out. All the needles on the
inside are drying beginning with the inside. Now I can
tell that what I thought was one plant is actually MANY
plants, probably at least 4. I may have watered it too
much as well recently as I freaked out when I saw the
plant drying out. Also, the roots seem to be coming out
of the bottom hole in the pot, so I think it is rootbound. Should I repot the mass of multiple plants?
Or divide them and plant in new pots? Should I prune it
back some? Any advice? I love this plant!!! JP
I think I would just repot
the whole plant into a container that is just the next
size larger. Once transplanted, give it a light dose of
fertilizer and water regularly but not too much. Make
sure it is getting plenty of sunshine and prune a bit as
needed for cooking.
Hi. I am going to be moving and
leaving behind a beautiful (and HUGE) rosemary bush. Is
there anyway to cut part of it off to take with me to
transplant somewhere in my new yard? Thanks! MW
It hurts to move and
leave your babies, doesn't it. See the link in a similar
question on the "Gardening
Q&A Page" for help in taking part of your rosemary
to your new home.
I have a rosemary bush that is
about 3 1/2 feet tall and the bottom part looks dead and
has dead needles...but it puts out new green growth on
top...I am afraid the dying bottom will creep up to the
top. If I cut it back I am afraid it will be all dead.
In general rosemary won't
green back up once it has gone dry. You could try an
experiment: Cut back a couple of the dead branches and
see what happens.
I have purchased two rosemary
plants and both started turning black and tiny "bugs"
fly off which are grey in color.... what are they and
what can I do to keep my plants healthy??? The first was
destroyed so the 2nd did not get the "bugs" from the
It's hard to say what sort
of bugs you might have. The plant's appearance and the
bugs may not actually be related. If you are planting
outdoors (or even in a pot) you could have trouble with
Dear Sir, When I went to my
garden center to my surprise I found 8 different kinds
Can you tell me the best type for cooking (the one I
bought does not have a good flavor of rosemary). Thank
Out of curiosity I checked
my Territorial Seed catalog and they, too, have six
different types of rosemary but say they all are good
for cooking. I'm not aware of a single type that is best
for cooking. One thing to look for when buying herb
plants is to make sure they are not labeled
"ornamental." It is always a good idea to take a little
taste of a plant before you buy (just be discreet and
don't tell anyone I said to do it!).
Not really a question, but just a comment to say thanks to your Q&A Section I have probably saved my Rosemary plant. It developed a symptom you described as powdery mildew. Thanks to only two days of spraying with a drop or two of dish soap and a drop of vegetable oil in my mister of water, it seems to have completely "whacked" back all sign of the mildew. Many thanks as I love my Rosemary plant, where would my omlettes be without it! I guess one question as well, despite the fact that I think the soil it's in in its pot may not be the
best--too sandy and too dense with perhaps with not enough drainage--it seems to be happy. Should I upset it and transplant it to soil with more drainage? Especially as it will have to come indoors soon I would think as fall and winter near? Best and thanks, enjoy your site tremendously....P in NJ
Thanks for your kind words. It
always makes me happy to hear how folks are using the site. As for the soil,
rosemary actually seems to thrive in poor conditions so it is probably better
not to fiddle.
My rosemary, as well as some of the sage plants get globs of a liquid white foam on them. Tonight I washed hundreds of globs from the rosemary in particular. Last year, the other rosemary had the same problem. What is that? Thanks J
Sounds like spittle bugs to me. You are doing the right thing by washing them away as the nymphs are hatching in the foam.
Hi, my trailing rosemary has some type of bug that's pulling together the leaves and producing kind of a cobweb on them. Looks like it loves the new growth tips. I picked apart one and found something that looked like a dark centipede or millipede. I'm thinking maybe something laid eggs in there? Everywhere the leaves are pulled together turns brown and dies, and the plant's really starting to look sad. I don't want to spray chemicals, because I was planning to use it for cooking. What should I do? AB
Sounds like you might have a case of garden webworms. They form that web and then feed on the enclosed leaves, that's why they die. The best defense at this point in their life cycle is to pick them off the plant and drop them in soapy water.
Hi! I just purchased my first rosemary plant..it's just about 7 inches tall. When can I start using it for cooking, and also, when should I bring it inside (I live in Seattle, WA)? Thank you! TJP
You can start using it anytime just be careful not to take more than a quarter of each branch at any one time. You may not need to bring it indoors at all unless the temperatures fall below 25 degrees F. I live just north of you and my rosemary that is in the ground made it
through last winter beautifully.
Hi, I just purchased a small rosemary plant, it's been about a month. How long can I keep it in the same pot or change to a larger pot. Converse, Texas Thank You.FH
If your rosemary is still in one of the smaller, 2 or 3 inch, pots that most plants are sold in, you will want to transplant it to something larger.
Rosemary is one of my favorite herbs to grow, dry, and use for culinary purposes. Yet in many recipes, the needle-like leaves create an unpleasant texture in the finished dish. This year, after drying my rosemary, I pulverized the leaves in a food processor, creating a very fine
consistency. I'm hoping that this powdered rosemary will produce better flavor and texture. However, after some research on the Web, I'm wondering whether the more concentrated, powdered version is safe for culinary use? CB
Interesting question but I don't think you have anything to worry about. I checked Rodale's Illustrated Encyclopedia of Herbs, a reliable source for dosage warnings, and came across a mention that when large quantities of the pure oil are used therapeutically it may irritate the stomach, intestines or kidneys. You are probably getting less of the essential oils than you would in eating the rosemary fresh since both drying and grinding diminish them.
Can rosemary be frozen for storage...... (fresh rosemary) or what is the best way of storing this amazing herb? Thank you, have a blessed week
You could freeze branches of rosemary or strip the needles, spread them out on a baking sheet and freeze them that way too. Once frozen, you can gather them into a bag for storage. The texture will probably change slightly turning a little mushy but the flavor will be good. Rosemary can be dried by hanging a bundle of stems (upside down) in a dry well-ventilated area.
Hi, My rosemary bush is huge! Its about 6 or 7 feet across, and separates out yard into two separate places, so I want to cut it way back, and possibly move it to the side of our yard by the fence. The problem is it is full of bees, and I am a little scared to get too close to it, let alone go hacking at it, any suggestions on getting rid of the bees so I can trim the bush, and also move it? Please advise! Thanks, M
Please don't hurt the bees, they are just doing their
job. Please see the article "What's the Buzz about Bees?" It would be better to cut your rosemary back after it has finished blooming anyway. Although I have no experience with an herb plant of this size, the rule of thumb with most plants is not to cut more than one third of any plant at one time. As for moving the plant, I suggest you contact your local master gardeners San Diego Master Gardeners for information on the best time and way to do so.
I have a small rosemary plant that is about 6 inches tall. What is the best way to harvest this? Should I cut off whole pieces of the branches or just pick each individual leaf? What method would be the best way to maintain the plant's fullness and growth? If picking individual leaves, should I pick just the leaf, or pick it with the little stem that attaches it to the branch? Thanks!
You will want to snip sprigs from the branches of your rosemary. This means cutting
into the stem just like you are cutting back a houseplant to encourage bushiness. The most important thing to your little plant right now is that you shouldn't harvest more than one third of the plant at a time. Once you have snipped off the sprigs you can strip the individual leaves, or needles, from the stem if it is tough or just chop the tender stems right along with the leaves.
Hi, I love all plants as well as herbs. I live in NYC, I purchased a rosemary plant in December. I have it in a window (facing west) it is now starting to die. The window also is above my radiator, could the dry heat be killing it or is there something else that has caused it to die. I love these plant/herbs, what's the best way to keep them in good shape. Thanks R
The dry heat from your radiator probably isn't good for the plant. You might try misting it every now and then.
Mid-winter is a sort of dormant period for rosemary. Don't water it too much (but don't let it dry out completely either) and in about a month start it on a regular program of liquid fertilizer.
I have a recipe that calls for 1/4 cup chopped rosemary. How many bunches should I buy? Thanks
One bunch should be more than enough. To prepare it, grab each stem at the top with one hand and pull down using the fingers of your other hand to strip the "needles." Give it a rough chop on your cutting board and transfer it to a measuring cup.
Hi, I was wondering how much I can safely cut back my rosemary without killing it. It is about 7-8 feet tall and was growing wildly in our backyard when we bought our new house. It is really not bothering us, and we actually love the look and smell of it, but we want to make sure it continues to thrive. Is it okay to just leave it alone, or does it need to be trimmed, and if so how often? DP from Texas.
Most herbs thrive on being trimmed every now and then but your rosemary is beyond being an "herb plant." The biggest, most beautiful rosemary bush I ever saw was in the parking lot at one of the San Antonio missions and I don't think anyone was paying it a bit of garden attention. I say, do whatever you want with yours!
My wife insists that it is dangerous to add rosemary to anything unless it is in a bag. She says that rosemary is a choking hazard. I can see a choking if someone tried to eat a whole sprig but will the leaves cause a problem? CL
I am not aware of anyone ever choking on rosemary leaves but I find they are more palatable if given a rough chop before adding to a recipe.
Hello. I just bought a small rosemary plant last week. Today I noticed that there is white liquid "puss" coming out of the stem, just at the base of the needle growths. Any idea what the problem is and how I can solve it? Thanks EO
That sounds pretty unusual. Are you sure that it is a liquid rather than a growth? It might might be mealy bugs which are sort of cottony looking. I think I would take that plant back to where I bought it.
How does one go about cutting the plant Rosemary and drying it. I thought that as long as I grow it, why not dry it, so I can use it later on for cooking purposes. Thank-you. JB
You will want to follow the "rules" for trimming your rosemary: don't take more than one-third of the plant at any time and make your cuts just above a leaf joint. You can dry it just like any other herb. That is, by hanging tied bundles upside down in a
cool dry place or stripping the leaves and arranging them on a screen for good air circulation also in a cool dry place. Just be sure to leave the branches or leaves until they are absolutely, completely dried before storage or they will mold.
I have a small rosemary bush in my front bed. Its so close to the walkway now and I am thinking of moving it. It is about three feet tall and about as wide. Is it ok to move it and if so, what is the best way. JI
You could transplant your rosemary bush in the same way you would any other perennial or bush. Dig a wide hole around the base of the plant working your shovel under the root ball as gently as possible to avoid breaking roots. Transfer the plant to its new location as quickly as possible to avoid letting the root ball dry out. Water it thoroughly and give it extra attention as it adjusts to its new location. This entire process is better done in cool weather.
I live in central Florida and am trying to grow a rosemary plant in a pot. The lower leaves on the plant are yellowing but the upper leaves seem fine. I've grown rosemary in New Jersey by keeping them potted indoors in the winter and moving them to the garden for the summer without problems. If you can tell me what causes yellowing leaves in rosemary
I'd be appreciative. Thanks, KHL
Yellow leaves are often a sign of overwatering in plants. You might also try giving your rosemary frequent feedings with a seaweed based fertilizer.
I have two rosemary plants. Both flowered the first year and have not flowered since. (one plant is 2 years old, the other 1 year). They are growing well, about two feet tall. I have never pruned them. How do I get them to flower again? A from Arizona
Personally, I have never had a rosemary plant that flowered but like I always say, I'm a much better cook than I am a gardener. One thing I can think of, however, is that perhaps you are fertilizing too often? This will sometimes stimulate more foliage than floral growth. Rosemary needs very little fertilizing if it is grown in good soil.
I bought a small rosemary plant about 4 years ago and planted in a small bed along the house. It is gorgeous, about 3 feet tall and about 3 feet side. It is close to the edge of the walk way so I have thought about pruning it, but I don’t know if I should divide the plant using a shovel, or prune it back. Any help appreciated. RC
I've never heard of dividing rosemary so you would probably be better off just pruning it back. Don't take more than a third of the foliage off at any one time.
Is it OK to cut back my rosemary bush? How much? I live in Arkansas it thrives all year, but is leaning forward a bunch because it is so heavy. Is it ok to cut it back and how close to the ground. I am zone 7.
Lucky you, sounds like a nice bush! It is best not to harvest more than one-third of any plant at one time.
I got a small rosemary plant at Christmas and it was fine.
Wasn't sure how to take care of it, but thought it should be more tolerant to dry versus wet soil. Unfortunately, the leaves began to turn black, then dried up and began to fall off. I watered it heavily, let it drain and it got worst, then died. What did I do wrong? I would like to grow one outside this spring in a pot. MG
The problem with your rosemary plant could very well be nothing in particular
that you did. I suspect that sometimes plants just don't adapt well to the
transition process from the well-cared-for-by-professionals at the nursery to
the final destination in our gardens or homes. Add to that the care, or lack
thereof, taken in the retail environment, some plants just aren't going to
make it. Do try again this spring to grow one outside. Buy a plant from a
reputable nursery and ask them about how to care for it. Read more about the
problems other folks have come across, see other questions below. Rosemary is one of the most wonderful herbs to have in the garden--good luck with your next one.
What are the benefits of a pinch or two of Rosemary in the bath. Have very dry skin problem and was wondering if it might help that problem. Thank-you S.Z.
My copy of Rodale's Illustrated Encyclopedia of Herbsactually has an entire entry called Bathing with Herbs that I hadn't really noticed before. Although it makes no mention of herbs specifically as a remedy for dry skin, they do list rosemary as an
astringent herb so this may not be the best choice for you. As a moisturizing bath, they suggest a homemade bath oil made from three parts vegetable or nut oil and one part herbal oil (this can be purchased commercially). Another tip is not to add oils to the water until you have soaked for ten minutes and then not to soak for more than twenty minutes total.
I'd always heard that if you trim back rosemary, you shouldn't cut below the green growth, because, unlike a lot of other plants, rosemary won't put out new growth below the green leaves.
However, early this Fall, I'd thought that my rosemary was dying, since it was losing all it's leaves. I drastically cut it back, in many cases, cutting all the green off the stems, in order to be able to dry and salvage as much herb as possible. About a week later when I went outside to pull up the rest of the plant and discard it, I could see new green growth popping out all over! I left it and started watering again, and it looks like it's getting really healthy.....although with all the earlier pruning, it's not such a pretty shape at this point. So, we'll see what happens! I'm used to losing rosemary in the summer, since we live in central Florida, and the herb does not like the hot humid conditions here. RB
Thanks for your success story! Just goes to show, never give up on a plant.
I have a rosemary plant, that seems to be thriving well. I have repotted it over the summer into a larger pot as it has grown so much that is has bark on the main stem! The problem is, over the last few weeks, the leaves on some of the stems are turning black. What causes this and how can I treat
it? I’ve already lost one rosemary plant to this same thing 2 years ago. Thank you, JB
I suspect your problem is in the watering. Either not enough or too much. You
might also check the plant for scale which will sometimes result in sooty
mildew. Be sure to read through some other growing hints below.
I have a magnificent rosemary plant that is about 5 years old. Each summer, I bring it outdoors and each winter (zone 5), I bring it indoors in a sunny location. It has always done extremely well and has been admired by many. This summer, after it had been outdoors for a while, some of the branches started to die - the leaves turned black. I quickly trimmed those off and monitored the plant, but the process has continued. Since the plant had not been transplanted in a while, I put it into a larger pot (indeed, it was pot-bound), checking the soil and roots for any sign of pests or disease. Found nothing suspicious. Over the past 2 or 3 months, the dying process has progressed - very slowly. The plant is now back indoors for the winter but I'm afraid it will not make it. What can possibly be ailing it?
Thanks for any help offered.
Rosemary is susceptible to root rot so it should be kept in well drained soil but you probably would have noticed that when you transplanted it. I do know that if it is allowed to dry out too much it simply won't recover. I have had this happen to individual branches of a plant. I'm afraid I can't be of much more help and I'm sorry if you lose your plant. You could try to propagate a few of the healthy branches to start new plants from this old favorite. Just take a few cuttings (but never trim more than a third of any plant at a time) and root them in soil.
How do I keep my rosemary alive thru Wisconsin winters? I used a plant protector this winter but my plant died. Can it be protected adequately outside or am I going to have bring it inside? I have a detached unheated garage which would allow some protection from extreme cold, would that be an option? Thanks, R
Rosemary cannot survive temperatures in the low 20's or below so you will need to bring it indoors next year. If you want to plant rosemary in the ground for this summer, you might consider planting it pot and all so that you can dig it back up.
NH - put the Rosemary outside in summer- its fine, when I bring it in the warm dry house, it gets very dry looking but gets powdery mildew. Seems like an oxymoron, I know. I'm currently trying pruning the effected areas and water, baking soda and a couple drops liquid soap in a spray. Any other hints? How often should I water inside. Its in a clay pot with a clay pot dish. I just added some small stones to hold the humidity since its on a radiantly heated floor.Can you search your q/a by key words? PO
You are doing the right things with your plant by pruning and spraying (although one recipe I saw that sounded similar to yours also added a drop of vegetable oil). Air circulation can also contribute to this fungus problem so you might make sure it's not crowded by other plants and even try a little fan. Make sure it is getting plenty of sun and water when the soil feels dry. Rosemary doesn't like wet roots so be sure to empty the clay dish after each watering. Watch for a newly organized Q&A section coming soon that will make it easier to find the information you want.
I'm growing Rosemary for my science project. I was
wondering how high a Rosemary could grow in a month
and if I should just purchase a already started to
grow plant. Any extra information would be really
nice. Thank You very much. KJ
I can't accurately tell you how much a rosemary plant
would grow in a month although I would predict just a
few inches. You should start with a plant for
sure because it is a difficult plant to grow from
seed. Be sure to see
All About Rosemary for more information on this
fragrant herb. Good luck with your project!
We live in Oklahoma and need to know how is the best way to store rosemary after you cut the plant down. Do we just let it dry out and then store it, so we could have it most of the winter, or just put in frig and keep it for a couple of weeks? Wanted it to last longer than that, but can't find any thing telling you how to do it. Couldn't leave it outside, it would freeze, correct? Thanks for your help, PL
Your rosemary plant should be able to weather cold temperatures as a hardy perennial (meaning it will produce year after year). Make sure it is completely dry before storing the needles in air-tight containers. It will keep for several weeks wrapped loosely in plastic and kept in one of your refrigerator drawers is possible.
What brand of soil should I use for my rosemary plant. LM Lake Forest, CA
Rosemary likes a well-drained soil with a pH of 6.5-7.0. Plant it in a sunny place that you want to keep it for awhile because it doesn't take well to transplanting. If you are going to plant it into a container, work a bit of sand into an all-purpose potting soil mix. Before planting in the ground, work the soil with sand and compost or other organic matter.
Hope u can help?? My rosemary plant has this white (looks) powdery stuff on it. Yet its only on the new shoots that grew in place of sprags I had pinched off earlier....I adopted this plant 4 years ago ( its almost 10 years old now) and have not seen this happen to it before. This white stuff is a little on the sticky side ... could this be a sap resin? or something to do with pollination? In the picture attached I circled to the new shoots and this white stuff is visible ...we have bad winters so it does come in during the cold months......and we just put it out about 4-5 weeks ago. Do you know what this whit stuff is???? (and its VERY strong in rosemary scent)
I suspect your plant has a problem with powdery mildew but am not positive. I suggest you snip off a sprig of the problem and take it to your local garden center as soon as possible for a positive diagnosis and treatment suggestion. Most pests and disease will strike the tender new growth first so that may explain why the problem is occurring where you have pinched.
Can you please tell me if I need to spray my fresh Rosemary wreath after I finish making it? Thank you, Helen
An article I read from Park Seed recently didn't mention spraying herbal wreaths but did suggest drying them well. They also recommend hanging the fresh wreaths in a place where they won't get knocked around to avoid "shedding."
