Preen Garden Weed Preventer Drum (16 lb.) is a powerful pre‑emergent solution designed to stop weeds before they begin to grow. Ideal for use in flower beds, vegetable gardens, ground covers, and around trees and shrubs, this long‑lasting formula prevents weed seeds from germinating for up to three months. Safe for established plants, Preen helps maintain clean, weed‑free garden beds with minimal effort. Simply apply, water in, and enjoy a season of reduced maintenance and improved plant growth thanks to reduced competition.
Creates an invisible barrier under the soil surface that prevents weed seeds from sprouting. Does not kill existing weeds—remove those before applying.
Use around established flowers, vegetables, trees, shrubs, roses, herbs, groundcovers, and ornamental grasses. Not for use on lawns.
Remove existing weeds, sprinkle granules evenly over the soil surface, and water in to activate. Keep granules off plant foliage to avoid discoloration.
One 16 lb drum covers up to 2,560 sq. ft., making it suitable for small‑to‑medium garden beds and landscaped areas.
Apply anytime in spring, summer, or fall. Best used early in the growing season before weeds germinate; reapply every 9–12 weeks to maintain weed prevention.
Approved for use around 200+ established plants, including most flowers, vegetables (after they are 2–3 inches tall), shrubs, and trees.
For best results, apply after mulching; rake lightly to integrate granules and then water to activate the weed‑preventing barrier.
Rain will not wash the product out once activated. Store in a dry place and reseal container after use.
WARNING: This product can expose you to chemicals including Trifluralin, which is known to the State of California to cause cancer. For more information go to www.P65Warnings.ca.gov
