Hand-pulling is possible for small patches but crabgrass drops seeds easily, making herbicide the better long-term strategy. Pre-emergent in spring is the gold standard.
Apply a pre-emergent herbicide (containing dithiopyr or pendimethalin) in early spring, 2–4 weeks before soil temperature hits 55°F consistently. If crabgrass already appeared, use a post-emergent (quinclorac) in spring while plants are young.
Mow at 3+ inches to shade soil and prevent germination. Maintain dense turf through fall overseeding.
Maintain thick, healthy turf through proper mowing height and watering—crabgrass thrives in thin, stressed lawns.
