Smart protection for a healthier, more resilient lawn

Meet Preen Lawn Crabgrass Control, a ready-to-use solution designed to guard your lawn from crabgrass and a broad array of common weeds. This formula aims to balance preventative power with post-emergence control, helping you maintain lush, even turf across seasons. The result is a greener lawn that still looks well-kept after rainfall or sun-drenched days in spring and summer.

With thoughtful formulation and flexible timing, this product supports a user-friendly approach to weed management. You can apply it before weeds germinate to reduce seedling establishment, and it also offers post-emergence control for seedling crabgrass for up to four weeks after it appears. This dual-action approach is designed to fit into varied lawn care routines without forcing trade-offs between killing and preventing weeds.

How to use and where it works best

Apply as directed to lawns and ornamental turfgrasses before weed seeds germinate to maximize prevention. For crabgrass that has already emerged, you can treat seedling crabgrass within four weeks of its appearance to reduce new growth and spread. This makes it a practical option for homeowners who want a straightforward weed-control routine without sacrificing lawn health.

Best results are achieved when the product is used on the following grass types: cool-season grasses such as creeping bentgrass, fine and tall fescues, perennial ryegrass, and Kentucky bluegrass; and warm-season grasses such as bermudagrass, St. Augustinegrass, carpetgrass, centipedegrass, zoysiagrass, and related varieties. The product is designed to work across a variety of lawn environments when applied per directions and paired with proper mowing, watering, and fertilization practices.

Real-life use scenarios

Imagine a front yard that stays green and weed-light throughout spring. Picture a backyard lawn where crabgrass tends to appear in clumps after warm periods, kept at bay by a single, season-long treatment. For homeowners with ornamental turfgrasses around flower beds or pathways, this product offers a practical option to protect those areas while keeping the turf visually uniform and inviting.
