Organic Crabgrass Control in Vegetable Gardens

Organic Crabgrass Control in Vegetable Gardens

No broadcast spray kills crabgrass without harming crops. Prevent germination in early spring with granular pre-emergent. For existing crabgrass: spot-spray herbicide carefully, or smother with black plastic + mulch in spring (cut X's for plants). Crabgrass is annual — dies in winter; prevent next year's seeds.

Organic Smother Method

  • Lay black plastic in spring.
  • Cut planting holes.
  • Cover with straw/leaves.
  • Also sterilizes soil.

Prevention beats post-emergence battle.
