Q.Japanese Beetles & Milky Spore
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.

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