Application

How to Apply

Watch how to apply Preen Garden Weed Preventer

When plants are dry, sprinkle this product on soil surface at rate given below for your specific planting situation. Once activated by watering, it forms a weed control barrier in the top layer of soil (1 – 2 inches), preventing weed seeds from germinating. Disturbance to the soil surface after activation may result in erratic weed control.

When to Apply

Apply Preen Garden Weed Preventer during the growing season around established plants and transplants. Preen should not be used on flower seeds. It can be used after flowering plants have germinated and are 2 – 3 inches tall. Preen may also be incorporated into the soil when seeding vegetables or applied after mulching beds. By applying Preen as early as possible, you can eliminate the need for hand‑weeding.

Rain does not wash this product out of the soil. To keep beds weed‑free all season long, reapply Preen weed preventer every 9 – 12 weeks.

Applying Around Established and Transplanted Plants

For flowers, roses, herbs, ground covers, ornamental grasses, shrubs, trees, and listed vegetables at least 2 – 3 inches tall, sprinkle Preen Garden Weed Preventer evenly over the entire soil surface, at the rate of 1 oz per 10 sq ft, being sure to keep granules away from plant roots and foliage. Immediately water. If watering-in is not convenient, lightly rake into soil surface. Always wash or brush off stray weed preventer granules from plant foliage to avoid damage or discoloration.

Applying with Mulch

For best weed control, we recommend applying Preen Garden Weed Preventer after spreading mulch on your flower and shrub beds. Sprinkle Preen on top of the mulch being sure to keep granules away from plant foliage. Immediately water this product into the mulch. If watering-in is not convenient, lightly rake into top layer of mulch. Always wash or brush off stray granules from plant foliage to avoid damage or discoloration.
