Block new weeds from sprouting for up to three months.

Keep weeds from germinating in your flower and vegetable gardens with this 5.625 lb shaker container of Preen® Garden Weed Preventer. It also works in ground covers and around trees and shrubs. Blocks weeds up to three months. Covers up to 900 sq. ft.

Preen® will not kill existing weeds, but prevents new weeds from sprouting, eliminating the need for difficult and time‑consuming hand‑weeding. Without weeds, plants grow larger and stronger.
