Crabgrass
Most Common Location:
Lawns, landscape plantings
Cultural Control Options:
Hand removal where limited number of plants are present, not practical for larger lawn areas; maintain minimum 2.5 to 3.0 inch mowing heights and good turfgrass density.
Additional Weed Control Information:
Lawn preemergence products should be watered in with about 1/4" to 1/2" of water right after application to improve effectiveness. Additionally, crabgrass can be controlled in summer with specialized post-emergent application.
