Japanese Beetles & Milky Spore

Question

Is to too early to apply milky spore to me lawn to control Japanese Beetle grubs? I have a new Japanese Maple (Fire Glow) I’d like to protect. I have been enjoying, and learning from, your emails for the past year.

Answer 1

It works best when the grubs are actively feeding, which is late summer to fall. This article will help:
