Lemon Tree Problem - Help!
Hi, We have a lemon tree that is probably around 30 years old. We've lived here for almost five years and the tree has always been healthy during that time. This year, there is something very wrong with it. (Please see attached photo.) 1) The leaves turn pale, from the edge inward; 2) then brown spots appear; and 3) I just noticed that something is laying eggs on it and eating the leaves but this is probably not related. It has been a hotter than normal summer here but other than that, nothing has changed. If anyone can tell me what is wrong with this tree, I'd really appreciate it. Thank you!
