I live in NY,
what is the best time to lay down that fast acting grub killer?. in ny they do not sell the season long killer due to chemical in it. I put down Milky spore 2 weeks ago (4x4 grid type), but that will take awhile to be set in lawn and I want to be proactive before grubs eat my lawn... if I applied it now June 25th is it too early and wasting time/money or it it safe to assume that the grubs are already eating my roots?
thanks
