Curling apple leaves
I have been lurking for a while, enjoying all your posts
I have 2 young apple trees which have never blossomed or set fruit. The leaves are curling, like a taco. Curling UP, on either side of the main vein of each leaf.
I can't find something that looks like this anywhere on the net.
I am in Phoenix and it is hot as heck here already. I believe I am watering adequately, but you may know better.
Any ideas what is wrong?
One is granny smith, and the other I cannot remember! It's probably written down somewhere....
