Young crabgrass setting in asparagus patch
I have three rows about 25' long of asparagus. Inbetween the rows I have weeb fabric and playground mulch to keep the weeds down. Well the crabgrass is growing thick everywhere. Im working out of town during the week now and only have weekends to weed. What can I do to keep my head above water? I was thinking round up since it is a root. Or I could just let it grow and worry about it next year. Im not an organic type of guy. So if you know of a chemical to treat please help.
