OK. Call me stupid if you like. When I answered first time, I could only see the second picture. The first one came up as a bad link. So I just went back and rechecked the pix. I still don't have a great idea of what has happened to your trees, but is there any chance you have had a late frost? A number of our local nurseries have been discounting JMs because they got them from southern growers, and a late frost damaged and killed a lot of the leaves. So the trees look ugly, and rather than just pluck the bad leaves and let them grow back in, they've decided to cut the prices. Just a thought because you did mention it being windy and cold.
