why is crab grass called crabgrass
Crabgrass is a light green, weedy grass that can appear in summer. Crabgrass and other annual grassy weeds are common problems in home lawns that can be treated through chemical and nonchemical methods. Proper lawn care practices to encourage a dense stand of vigorous grass are the best way to prevent weeds from invading. For example, mowing height can have a big impact.
