10 Best Pre Emergent For Bermuda Grass 2025 in the United States

The Preen Garden Weed Preventer is a granule-based product and comes in a 22 lb. bag that can cover up to 3,520 sq. ft., which is quite extensive. One of its major strengths is its ability to prevent new weeds from sprouting for up to 3 months, saving effort on hand-weeding and making it suitable for busy gardeners.

It is also versatile in terms of application as it can be used in spring, summer, or fall, and is safe around over 200 different types of established plants including flowers, vegetables, trees, and shrubs. This flexibility can be particularly beneficial for those with varied garden types and schedules. The product is easy to apply and can serve as a refill for a flip-top applicator, which adds to its convenience.

However, there are some drawbacks. The product is not intended for use on lawns, meaning it is not suitable for those looking specifically for a pre-emergent for Bermuda grass on their lawns. Additionally, its specificity to garden beds rather than lawns limits its use if your main concern is Bermuda grass lawns. The residual effect lasts up to 3 months, which is decent but may require reapplication for year-round protection. Considering these points, the Preen Garden Weed Preventer is ideal for gardeners looking to maintain weed-free garden beds and plant areas, but not the best choice for those needing a solution for Bermuda grass lawns.

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is a solid choice for anyone aiming to maintain a healthy Bermuda grass lawn while keeping unwanted weeds at bay. One of its main strengths is its dual function; it acts not only as a pre-emergent weed killer but also provides fertilizer, helping to promote a quick green-up after winter. The active ingredients effectively target common weeds like crabgrass and others, ensuring a cleaner lawn come spring.

Application is straightforward; it’s suggested to be used in early spring before the grass has been mowed a few times, which is crucial for its effectiveness. It can be applied during various weather conditions, including rain or snow, without losing its potency, adding to its convenience. The coverage area is impressive too, with one bag treating up to 15,000 square feet, making it a cost-effective option for larger lawns.

However, it comes with a few drawbacks. For starters, it cannot be used on certain grass types, specifically Dichondra and Bentgrass, which may limit some users. Additionally, timing your application is critical; if you miss the early spring window, you might not get the desired results. While it's designed for a wide variety of weeds, some users might find it less effective on tougher weeds that may require additional treatments.

Scotts Halts Crabgrass & Grassy Weed Preventer is a granular pre-emergent weed control product designed to cover up to 10,000 square feet, making it suitable for large lawns. One of its main strengths is its long-lasting effect, with a single application in spring preventing crabgrass and other problem weeds throughout the season. This is particularly convenient for users who want a low-maintenance solution to weed control.

Its versatility shines through as it can also be applied in the fall to prevent winter weeds like poa annua, henbit, and chickweed, and even moss. This dual-season application is highly beneficial for year-round lawn care. Another advantage is its resilience to weather conditions; rain, snow, or freezing temperatures won't diminish its effectiveness, adding to its reliability.

The granular formulation is easy to apply but may not be as precise or customizable as liquid formulations for spot treatments. The product's weight and packaging size (20.12 pounds) also mean it may be cumbersome to handle for some users. This product is well-suited for homeowners with large Bermuda grass lawns looking for a straightforward, long-lasting weed control solution.
