The rosemary I grow from seed, has no resistance to cold. It whithers away and dies. Thats not to say yours is the same strain. For me, I cut off the branches and remove the needles and dry them in a dehydrator, then seal in a glass jar under vacuum. They keep quite well as does dill weed which is now 2 years old and still string flavored and deep green.

Hunktop, the needles which are black are beyond saving. however, the branches they are on might be okay. Strip off the blackened needles. Find a cool, sunny place for the rosemary indoors. Nevermind the outdoors for the rest of the season. I have four rosemaries which I over winter indoors and put out on my deck for the summer. They do well and even bloom indoors. I am in zone 5 and rosemary just isn't hardy here. Rosemary did very well outdoors when I lived in England and the High Desert.

Thank you so much ksrogers and herbalbetty. I'll try getting the needless off of it and hopefully the spot by the window will be sunny enough (and cool enough).

We keep the house at about 68 degrees, and this spot is away from the heat vents. As much sun as possible comes through the window, but we get a lot of grey days here in Ohio, and we're close to another house on that side so there's limited sun.

What do you think?

Also, what happens if I DON'T pull the black needles off? This is a rather large plant and pretty much every needle is black. Will they eventually fall off and the stems will be ok, or will the dead tissue spread into the stems?

Thanks again!

Huntkop,
The needles will fall off, and there will be no "spreading" of tissue damage to the limbs. However, the needles will make a mess in the pot and possibly start to mold from the dampness in the soil. Whatever you do, don't fertilize! The plant is stressed and doesn't need to try to grow right now.
