Pre-Emergent Herbicide Options for Vegetable Gardens

A gardener wanted to prevent weeds in a vegetable garden before tilling, listing tomatoes, okra, peppers, melons, squash, beans, strawberries, and blackberries. The expert recommended trifluralin (sold as Preen 'n Green), which is labeled for many vegetables. Apply and lightly incorporate into soil one week before planting. Always read and follow label directions for specific crops and timing.

Trifluralin controls many annual grasses and broadleaf weeds but does not affect established perennials. It must be activated by rainfall or irrigation. Combine with mulch and prompt cultivation for best results.

Important: Check the label for each crop—some vegetables have restrictions or require specific application methods.
