Aside from the persistent crabgrass, Bermuda grass and horse weed that are jealous of my irises having their own space, the worst pest has been Japanese beetles. I'm surprised nobody else has mentioned them here. They've invaded my fruit trees and rendered them into skeletons especially the cherry and plum trees. My roses were also badly affected. I'm wondering if anyone else has been successful in getting rid of these beetles. There are many methods but all have their drawbacks.
