What Chickweed Looks Like
Chickweed grows low to the ground and can form soft, spreading mats in the lawn. It has small green leaves, thin stems, and tiny white star-like flowers. It is often most noticeable in late winter and spring before warm-season lawns fully green up.
Why It Spreads
Chickweed thrives in cool, moist conditions and often spreads in thin, weak, or shaded areas of the lawn. It produces seed and can quickly fill open spaces where turf is not dense enough to compete. Overwatering, poor drainage, low mowing, and bare soil can make chickweed worse.
How to Prevent It
The best prevention is a thick, healthy lawn with fewer open spaces for chickweed seed to germinate. Improve turf density with proper mowing, fertilization, watering, and seeding or plugging bare spots when appropriate. In lawns with recurring chickweed pressure, a labeled fall pre-emergent may help reduce winter annual weeds.
Best timing: Fall, before winter annual weeds germinate.
How to Control It
Chickweed is usually controlled with a selective broadleaf weed control product labeled for chickweed and for your specific lawn type. Best results usually come when chickweed is young and actively growing in cool weather. Mature, matted patches may require more than one labeled application. Always read and follow the product label.
Best timing: Fall through early spring when chickweed is young and actively growing.
Recommended Solution
Step 1: Confirm the weed is chickweed by looking for low mats, small green leaves, thin stems, and tiny white flowers.
Step 2: Check your lawn type before choosing any weed control product.
Step 3: Treat chickweed while it is young and actively growing, usually in fall, winter, or early spring.
Step 4: Use a selective broadleaf weed control product labeled for chickweed and your specific turfgrass.
Step 5: Recheck the area after treatment. Thick patches may need a second labeled application.
Step 6: Improve thin areas with proper mowing, fertilizer, watering, and seeding or lawn repair where appropriate.
