I have several rosemary plants that I have been growing in pots for years. This year, I finally decided to plant them in the ground as they were getting too big for their pots and finding space for them indoors has gotten very challenging. My concern is whether or not these plants will survive the winter outdoors, how much mulch I should be using on them and whether or not I should cut them back. I am in zone 6b and have read mixed reviews about rosemary in my area and any local/regional help is greatly appreciated.
I just bought a rosemary 'Arp' and I'm going to give it a try. wish I could be more help. I'm going to put it in a sheltered place near some large boulders. Figured it would stop the wind and help hold some heat.
Very infrequently have I had any make it over winter and 'Arp' was a big disappointment. Heat does help and I've read that rocks (many rocks) around the base will help them live over winter. I guess they hold the heat but thinking that it would be enough is hard to imagine. Worth a try!
I put in a 'Hardy Hill' rosemary this year next to a big rock close to the house on a southern exposure. It is supposed to be heartier than Arp. I have lost every other rosemary I put in - but I did them in a parking strip where the were really quite exposed inspite of heavy mulching. I will add some additional rocks around it and lots of leaves and keep my fingers crossed. Rosemary is classed as a 'tender' perennial - guess Connecticut isn't in the tender zone.
I know this is an old post, but thought I'd update everyone. One of the rosemary plants I planted outside managed to survive and barely so. All the branches from last season are dead with the exception of the bottom layer that is making a nice comeback. Does anyone else who experimented with rosemary in our zones managed to successfully overwinter them outdoors?
I had the same thing happen with a rosemary I keep inside in a 14" pot. It bloomed at Christmas. Looked good until March, then all the branches except one small one at the bottom appeared dead. Have it outside and one more small branch down low is green but most of the plant looks gone.
my 'Arp' survived the winter with some green still intact, but a later freezing may have done it in. I don't see any new growth on it and we had another frost last night. I have to admit I never did give it the extra mulch I intended. so if it didn't make it, I will try again this year. I'll report back here after I give a little more time. it may still come back. it was a very small plant.
I had an arp survive a couple of winters but it always died back (mostly) to the ground. I want to try again because it's such a delight to use the leaves fresh, even IF it's not supposed to be the best culinary variety.
Me, too, but it's not the same. I know I once read the story of how it got that name but being an AARP person I'll be darned if I can recall it now. Probably at 3 A.M. I'll think of it and give you a call.
