10 Best Weed Killers For Lawns 2025 in the United States

Scotts Liquid Turf Builder with Plus 2 Weed Control is a liquid weed killer and fertilizer that combines weed control with lawn nourishment. It is designed to kill various broadleaf weeds, including dandelions, clover, and poison ivy, while providing a nitrogen boost to the lawn. This product is easy to apply with a ready-to-spray formula, targeting active weeds effectively.

It is suitable for several types of grass, such as Bluegrass, Fescue, and Bermudagrass, making it versatile for different lawn types. A 32 fl. oz. container covers up to 6,000 sq. ft. for warm season lawns and 4,000 sq. ft. for cool season lawns, which is fairly efficient coverage. However, users should be mindful of the timing of application, as it is most effective when weeds are actively growing.

Additionally, while the product combines weed control and fertilization, it may not be suitable for those looking for an organic or eco-friendly option, as it contains chemical ingredients. Its dual functionality as both a weed killer and fertilizer can be a strong selling point for those looking to save time and effort in lawn maintenance, but it may require careful handling to avoid potential environmental impact or safety concerns.

This product is a liquid spray and comes with a Comfort Wand applicator, which makes it easy to apply with precise control and no need for pumping. Users will appreciate the quick results, as it shows visible effects within hours and is rainproof after just one hour of drying.

Additionally, it is safe for use around people and pets, who can return to the treated area once the spray has dried. One of the major strengths of this weed killer is its selectivity; it targets weeds while sparing the lawn when used as directed. This is achieved through the use of three proven weed killers. However, it's important to follow the label instructions closely to avoid any potential damage to the lawn. The product covers a substantial area, up to 16,000 square feet, making it suitable for larger lawns.

On the downside, some users may find the product's weight (9.4 pounds) a bit cumbersome, and there are concerns about its environmental impact, as it is a chemical herbicide. Additionally, while the Comfort Wand applicator is a handy feature, it may require careful handling to ensure even application. With a strong customer rating of 4.1 out of 5 stars, it appears to be a reliable choice for those looking to maintain a weed-free lawn with minimal effort.

It is critical to note that it is not suitable for all types of grass.

This limitation could be a drawback if you have a diverse lawn or garden. Additionally, while it kills weeds effectively, the product's environmental impact is a consideration; it’s always a good idea to use herbicides sparingly and responsibly.

If you're looking for a weed killer that is easy to use and provides rapid results for a typical lawn, Ortho WeedClear could be a strong option, especially if your grass type is among those it’s safe for.
