10 Best Weed Killer That Does Not Kill Grass 2026 in the United States

Scotts Liquid Turf Builder with Plus 2 Weed Control is designed to target broadleaf weeds like dandelion, clover, and poison ivy without damaging common lawn grasses such as Bluegrass, Fescue, Ryegrass, and Bermudagrass. Its active ingredient is nitrogen, which primarily serves as a fertilizer rather than a harsh chemical herbicide, making it a mild and lawn-friendly option. The product comes in a ready-to-use spray form, which makes application straightforward and convenient for most users. It's best applied when weeds are actively growing to maximize effectiveness. Coverage depends on the type of lawn: it treats up to 6,000 square feet on warm-season grasses and about 4,000 square feet on cool-season grasses.

One of the strengths of this product is that it combines weed control with fertilizer, helping to improve lawn health while managing weeds. However, it may not be as strong as some herbicides with more aggressive active ingredients, so very tough or stubborn weeds might require additional treatments. Also, since it targets broadleaf weeds specifically, it won’t affect grassy weeds or other non-broadleaf plants.

This product is well suited for homeowners looking for an easy-to-use, selective weed control solution that also nourishes their lawn, rather than those seeking a powerful or immediate weed eradication.

Scotts Turf Builder Weed & Feed3 is designed specifically for lawn owners wanting to eliminate common weeds like dandelion and clover without damaging their grass. It combines a selective herbicide with a fertilizer, which not only controls over 50 types of weeds but also helps thicken your lawn for a healthier, lush appearance. The active ingredients, 2,4-D and Mecoprop, target broadleaf weeds while being safe for a variety of common grass types such as Bermuda, Bluegrass, and Fescue. Application is straightforward—spread granules evenly over a wet lawn when temperatures are between 60°F and 90°F, typically in growing seasons. One 14.29-pound bag covers up to 5,000 square feet, making it suitable for medium-sized lawns.

It should be used no more than twice a year and is not safe for certain grasses like St. Augustine and Bentgrass, which means it’s not ideal if your lawn includes these types. Some grasses may also experience temporary discoloration after application. This product suits those looking for a combined weed control and lawn feeding solution that is easy to apply and effective on common lawn weeds, but it’s important to check your grass type beforehand to avoid damage. If you have a large lawn or need more frequent treatments, you might need additional products or solutions.

Preen Extended Control Weed Preventer is a granule-based selective herbicide designed to block weed growth for up to six months with just one application. It contains Isoxaben and trifluralin, effective active ingredients that target weeds without harming established grasses, making it suitable for use around many perennials, shrubs, and trees. The included scoop applicator helps apply the product evenly over an area up to 2,245 square feet, which is quite generous for most home gardens.

This product should not be used on flower seeds, lawns, vegetable gardens, or edible plants, which limits its use if you want to protect those areas. Additionally, it’s not available in some regions like New York. Because it prevents weed seeds from germinating, it’s best applied early in the growing season or before weeds appear.

For someone looking for a simple, effective way to stop weeds without damaging their grass or landscape plants, this product offers a convenient and long-lasting solution. Users should keep in mind the restrictions on where it can be used and follow the label instructions carefully to avoid unwanted damage.
