Planting, Growing, and Harvesting Rosemary Plants
Hi I have a very large Rosemary plant outside and right now it looks like it is dying there is only a little green left. Are they supposed to look like this at this time of year? Should I cut it back to see if it gets better?
Hi Lisa, Thanks for writing in. Rosemary is a plant that thrives in a Mediterranean-like climate and does not do well in locations with cold winters. It is not uncommon for its branches to appear dead in early spring. Since there is a little green remaining, that is a positive sign. To determine if a branch is dead, scrape the bark of a few stems. If the stem is green underneath, new growth is possible. If it is brown, removal is necessary. If all branches are brown underneath the bark, it is best to remove and get a new plant.
I planted seeds, many knowing germination can be low, and I have about 25 seedlings in a 7in diameter pot! They have just started their second set of leaves. Some are spindle-y-lanky some have nice thick stems. I have been leaving them outside all the time and they seem to be loving this spring in Maryland. I am wondering at what point to I thin them? Do I have to thin them? Amazing that this isn't info I could find on the internet! Thanks in advance!
It depends on how fast you plan to use the rosemary somewhat. For a 7 inch diameter pot, I would definitely reduce this to 5 plants maximum. I would not let them get very big either, maybe 6 inches tall, as they will begin to bush out at that point, and you can then liberally cut off sprigs to use in recipes, taking no more than a third of each plant. if you choose to keep all season or over winter, I would not have more than one in that small of a pot. Hope this helps
I’ve heard a honey bee keeper claim that a sprig of rosemary placed in a beehive will control & eliminate mites that wipe out honey bee hives! Does this work? & if it does, whAt is the proper procedure? Thank you!
I bought a rosemary plant and transfer it to a bigger pot, but within a week time the plant start to change it’s colour and now it died what I did wrong?
It’s possible that the soil was kept too wet or too dry after repotting, or the plant was given too much sunlight. Freshly repotted plants can be fragile!
I've been trying to grow rosemary from seeds for about two weeks now with no results.
They're planted in miracle grow with a small amount of herb fertilizer added, there's a heating mat under the seedling tray to keep it at 72 degrees, the soil is moist and I have a UV light for both the rosemary (when it sprouts) and lemon balm. The latter has grown very well, but nothing from the rosemary.
Is there something else I should try? Maybe some tips to share? I'm at a bit of a loss.
Thanks in advance! <3
Rosemary is notoriously slow to germinate even in ideal conditions—as much as 25 days (or more). Some sources say that the seeds should be barely covered, others say 1/4-inch deep in well-draining germination/seed starting mix. Another suggests using sand or vermiculite. The heat is good; some say 80°F to 90°F. The light is not needed until you see growth, and at that time you want to water minimally (rosemary is highly prone to dampening off) and provide ventilation. You should sow more seeds than you want/need; no only is the germination rate slow, it is low.
These are all reasons that growers start it from cuttings. But give it time—and let us know how it goes!
