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 germinating in flower and vegetable gardens, in ground covers and around trees, shrubs and more. Although Preen will not kill existing weeds, it will prevent new weeds from sprouting – eliminating the need for difficult and time-consuming hand-weeding. Without weeds, your valuable plants can grow larger and stronger.
WHEN: 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. One easy application of Preen Garden Weed Preventer keeps over 200 broadleaf and grassy weeds from sprouting for up to three months.
Reapply every 9-12 weeks to keep your garden weed-free all season long.
WHERE: 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. 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. FOR VEGETABLE GARDENS use Preen Organic!
