How it Works: Preen Garden Weed Preventers
Here's how our Garden Weed Preventers prevent weeds before they even sprout rather than killing them after they’ve already had the chance to grow.
Preen Garden Weed Preventer: Blocks weeds for 3 months. Guaranteed
The arrival of warm spring weather switches plants into peak growth mode. Weeds are plants, too, and unfortunately, they sprout and grow with a particular force in spring. Digging, pulling, and spraying herbicides are classic ways to deal with weed woes, but there’s another lesser-known, labor-saving option – preventing them in the first place.
This can be done by applying granular products called “pre-emergent herbicides” or “weed preventers” over landscape and garden beds. These products, such as Preen Garden Weed Preventer, stop many common weeds from sprouting without harming existing plants when used as directed.
Preen works best when it’s applied early in the growing season before weeds germinate, but can be applied anytime that weeds are growing.
To apply Preen, follow these steps:
A new version, Preen Extended Control Weed Preventer, is Preen’s longest-lasting weed preventer yet. It’s labeled for use around 600 plants in perennial flower beds; around groundcovers, trees and shrubs; and in xeriscape settings and rock gardens. Preen Extended Control Weed Preventer tackles many of the toughest weeds a gardener faces, including dandelions, crabgrass, field bindweed, white clover, chickweed, henbit, purslane, Carolina geranium, stinging nettle, horseweed or marestail, oxalis, spurge, lambsquarters, and more.
Unlike weed killers, weed preventers don’t harm surrounding established plants. Use directions on all Preen products spell out exactly which plants the product can be used under and around, which weeds are prevented, and how to apply the granules for each Preen product. Be sure to read the label to ensure you are using the best Preen product for your garden and landscape.
