something is eating my dahlia leaves and it isnt a deer. it appears to be some kind of little bug. what can i put on them so they dont have all these little holes in them? i have some phlox that looks the same way.
It could be a flea beetle if it looks like BB's have been shot though the leaves. They are little black beetles that jump like fleas and are usually found on the underside of the leaves. Sevin will control them and just about any other bug that eat on your dahlias. It will kill the bees too so you don't want to use it on blooms.
