What Crabgrass Looks Like

Wide, flat blades with a light green color. Crabgrass often grows in clumps and spreads outward from the center.

Why It Spreads

Crabgrass thrives in thin lawns, compacted soil, bare spots, and areas with poor turf density. It produces thousands of seeds each season.

How to Prevent It

Apply a pre-emergent before crabgrass germinates and focus on building a thicker lawn through proper mowing, watering, and fertilization.

How to Control It

Existing crabgrass requires a post-emergent control product labeled for your lawn type. Always read and follow the product label before applying.
