I have two plum trees and a pluot tree. Springtime after the the leaves all came out and greened up nicely and the flower buds became visible, all at once, seemed like the next morning there were no buds and all the leaves looked as though they had been hit by shot, all the leaves looked like lace. I got a jeweler’s loupe to look for critters, but there was nothing. Basically, this all happened overnight and, of course, since this happened, it meant no fruit. Now we are getting into summer and they all are getting new greenery and looking nice again. Only thing I can do now is wait until it’s time to prune. Any idea what causes this? Like I said, no critters that are eating the leaves, no apparent fungus, I am at a loss. Any help would be great.
Slugs or snails could be the culprits or cutworms of some type.
