Q.Japanese Beetles & Milky Spore

Zone Durham NC 27703 | Anonymous added on April 18, 2022 | Answered

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.
