Chickweed in New Fescue Lawn: Control Strategy

Tilling for fescue seeding brought dormant chickweed seeds to the surface, resulting in a dense winter carpet. Chickweed germinates September–November and competes aggressively with young grass.

Treatment Plan

1. Apply Weed B Gon Chickweed, Clover & Oxalis Killer at half strength.
2. Repeat in 4 weeks.
3. If needed, a third application a few weeks later.

Next fall, apply Portrait pre-emergent in early September and early November to prevent germination (note: this also blocks grass seed).
