I keep reading this over and over and yet I have crabgrass seedlings in
the thickest grass in my lawn. I mow to 3 1/2". Seriously annoying.

How thick is the thickest grass? Does sunlight penetrate to the soil
surface? Do you actually have crabgrass (Digitaria ischaemum or D.
sanguinalis) or do you have another weed grass?
