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.


How It Works

Creates an invisible barrier under the soil surface that prevents weed seeds from sprouting. Does not kill existing weeds—remove those before applying.

Where to Use

Use around established flowers, vegetables, trees, shrubs, roses, herbs, groundcovers, and ornamental grasses. Not for use on lawns.

Application Instructions

Remove existing weeds, sprinkle granules evenly over the soil surface, and water in to activate. Keep granules off plant foliage to avoid discoloration.

Coverage

One 16 lb drum covers up to 2,560 sq. ft., making it suitable for small‑to‑medium garden beds and landscaped areas.

When to Apply

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.

Safe Plant Types

Approved for use around 200+ established plants, including most flowers, vegetables (after they are 2–3 inches tall), shrubs, and trees.

Mulch Integration

For best results, apply after mulching; rake lightly to integrate granules and then water to activate the weed‑preventing barrier.

Environmental & Handling Notes

Rain will not wash the product out once activated. Store in a dry place and reseal container after use.
