With some help, healthy lawns can oust crabgrass
Crabgrass is an invasive weed that grows well in lawns that are lightly watered, underfertilized and relatively sunny. Preventing crabgrass with pre-emergent herbicides requires good timing. Applied too early, pre-emergents will be washed away, and applied too late, they are completely ineffective. Once crabgrass has taken root, nonchemical methods are the best means of getting it under control. Seven simple steps will help you create and maintain a crabgrass-free lawn.
