Weed killer that won't hurt cactus?
Hi all, we have a cactus garden in the backyard, and it's become infested with crabgrass. We've been diligently pulling it ever since we've seen it, but it's getting out of hand now. We're ready to give up and try the chemical approach. Does anyone know of a good weed killer that'll nix the crabgrass but won't hurt the cactus?
