Winning the War Against Crabgrass—Pre-Emergent Strategies

Crabgrass thrives in bare, thin spots, sprouting annually from seed. Pre-emergent herbicides are your first line of defense, blocking seed germination and keeping sprawling tufts at bay.

Timing Is Everything

• Apply when forsythia blooms for at least a week—typically March or early April

• Lawn should be moist but firm; water lightly after application to activate the barrier

• Avoid disturbing the soil thereafter; crust formation traps herbicide in place

Follow-Up Maintenance

Maintain a dense, healthy turf through proper mowing and fertilizing—an unbroken canopy naturally inhibits crabgrass from gaining sunlight and space.
