My yard is infested with crabgrass. Since last year I have been applying
pre-emergent control in early spring but the crabgrass keeps on increasing
every year. This summer, I sprayed the lawn with Bonide Crabgrass and Weed
Killer. It killed some of the crabgrass but it started to grow again. Now I am
manually uprooting as much as I can of it but am not catching up. Any advice?
