Weedblock stopped Jap Beetles & Grubs??!!
I'm flummoxed. I've got 7 peonies which have been annually attacked by Japanese beetles. I've used lures before and gotten 3-4 bags full, but still enough on the bushes to eat most flowers. I JUST bought milky spore but haven't applied it yet.
Low and Behold- so far- no beetles. And the peonies are blooming like crazy. The only thing I did differently this year was change the peony cages (double hoop) and applied a sheet of contractor grade weed block down the entire row of peonies. I just cut a hole for each plant 3 weeks ago before they bloomed. But still, the hole is letting the stray weed through, so it's not like there's a hermetic seal around the plant.
Does anyone know if weed block could've stopped the beetles from coming out?
