My lemon tree leaves are having a problem. They become scaly, in some cases they curl. Last year we had no fruit but that was due to a late freeze that killed all the blooms. So I don't know if that had anything to do with this problem. But it did start last summer and is still going on.

I have butterfly weed that did great two years ago. Last year bugs attacked & ate off most foliage & flowers. I kept trying to treat with pesticide but it didn't help. I am attaching some pictures that I took this afternoon. Any help will most appreciated.
