Is there such a thing as Apple Leaf Curl? I've heard of Peach Leaf Curl, but never Apple Leaf Curl, but I have something weird going on on a couple of my apple trees.

Some of the leaves are not forming in the normal flat fashion. They are sort of curling up on the ends. It's not like they are rolled up in a neat little cyclinder, instead it almost looks like they are melting - sort of like horizontal piece of plastic that is heated until it starts to get soft and then held in the vertical position so it melts back onto itself.

Does that ring a bell with anyone?

Thanks!
