The best time to fight crabgrass with pre-emergent herbicide is when forsythias tend to bloom. In the mid-Atlantic region, this is usually between April and May. Even if you're late to apply the herbicide, it’s effective as long as the crabgrass plant has fewer than five leaves.

Jet washing can wash away weeds without bending or kneeling to pull them. However, the results will likely be fleeting because the weeds will return unless you use a stronger method that takes them out at the root. Use a jet washer for short-term weed removal, but use a stronger method if you want to get rid of weeds for good.

Lawns with steep slopes can benefit from having quack grass. Quack grass's long roots and runners can help to prevent soil erosion on hillsides. Additionally, bird lovers may enjoy the fact that quack grass seeds are an attractive food choice for their avian friends.
