Help me out here guys. I bought a house last year with a 1 acre plus lawn. The lawn was completely neglected and I spent the last year really bringing it back to life. It was looking great until a couple weeks ago. I just got done planting some trees and flowerbeds, and noticed with every shovel full of black dirt, there could be as many as 10-15 grub worms. This seems like an pretty bad ifestation here and I'm looking for product advice since I just laid down a weed and feed prior to finding this out. there are bare spots popping up everywhere Thanks for the input. Captn.
