The Best Time to Treat Your Lawn for Crabgrass: A Step-by-Step Approach Crabgrass is one of the most persistent weeds homeowners face, and controlling it requires proper timing and professional-grade lawn care practices. The key to effective crabgrass control is prevention. Crabgrass germinates in early spring when soil temperatures consistently reach approximately 55°F, making early-season treatment critical. Applying the right products at the right time helps ensure a thicker, healthier lawn throughout the growing season. Step 1: Schedule a Pre-Emergent Application in Early Spring The most effective way to stop crabgrass is with a pre-emergent herbicide applied before seeds germinate. For best results, this treatment should be completed in early spring, typically when daytime temperatures begin to stabilize and ornamental plants such as forsythia start to bloom. Pre-emergents form a protective barrier in the soil that prevents crabgrass from establishing, significantly reducing weed pressure before it becomes a visible problem. Step 2: Support Weed Prevention with Proper Lawn Maintenance Once pre-emergent treatment is in place, maintaining healthy turf is essential. Proper mowing height, balanced fertilization, and controlled watering all contribute to a dense lawn that naturally resists weed invasion. Thick turf shades the soil, limiting sunlight exposure that crabgrass needs to grow. Ongoing professional maintenance ensures these conditions are consistently met throughout the season. Step 3: Address Breakthrough with Targeted Post-Emergent Treatments Even with preventative measures, isolated crabgrass can occasionally appear. In these cases, post-emergent herbicides are most effective when applied early while the weed is still actively growing. Targeted spot treatments help eliminate existing crabgrass without stressing the surrounding turf. When combined with proactive spring applications, this step-by-step strategy delivers long-lasting results and keeps lawns looking their best year after year.
