Weed Preventers

The best way to control weeds in the garden is to prevent them from getting started in the first place. Preen weed preventers have specialized formulas to keep weed seeds from sprouting around trees and shrubs in both northern and southern landscapes.

One easy application of Preen Garden Weed Preventer keeps over 200 broadleaf and grassy weeds from sprouting for up to three months. Your garden will stay weed-free all season long.

Preen Weed Preventer for Southern Gardens prevents weeds for up to four months with a single application, keeping your garden weed-free throughout the south’s longer growing season. Weeds rob desirable plants of water and other nutrients. Preen weed preventers stop weeds and eliminate time-consuming weed pulling duties. With Preen, you’ll be free to enjoy a beautiful, weed-free landscape.
