Preen Extended Control Weed Preventer is not a weed killer – it stops new weeds from sprouting. First remove any existing weeds that may be growing. Then apply Preen Extended Control Weed Preventer using the easy-to-use bottle with flip-top applicator-cap. Sprinkle the product granules on top of the soil or mulch at the rate recommended on the label. Once the product is activated by watering, it forms an invisible weed control barrier in the top layer of soil (1 – 3 inches), preventing new weeds from growing. If it’s not possible to water in the product right away, and no rain falls within two days, use a rake to work the product into the soil or mulch.
