Michael: This is not the kind of thing that can be predicted by your fellow growers. It's a wait and see situation. At least you seem to have a pretty good idea of what went wrong. Don Yellman, Great Falls, VA

Wind and cold damage is indicated when the edges of the leaves become distorted and turn brown. This occurs frequently in plants that may be in a colder climate than recommended or in a location with severe exposure. Provide protection from winter winds and winter sun. Note, boron poisoning or fertilizer burn will create the same symptoms except uniformly over the plant rather than just on areas exposed to the sun and wind. Removing leaves and disposing of them is only necessary when disease is the cause. In your case it depends on whether you consider the leaves unsightly. New leaves will be on the plant in a year or two. Don't remove more than 1/3 of the leaf area if you do remove unsightly leaves. The notch on the edge is weevil damage. Most gardens have some weevils. They are night feeders so most sprays don't work. Leaf spots have many causes but shouldn't be a problem.

Doona, please check your prior post. There is a link with an excellent explanantion of what probably ails your plants.

I thought cutworms cut down seedlings. I did not know they left damage like this. I assumed it was slugs, although I had it on pot feet, which usually short curcuits them. Ken, I'm not sure what you are talking about. I rearranged those leaves and took another photo. They are all "cupped". I could not get a clearer photo. (I may have to read the book that came with my camera if I keep taking close-up photos.) I was concerned about the spots on the leaves.
