Scotts Turf Builder Weed and Feed 3, 15,000 sq. ft.
Most important from
36127 reviews
Scotts Turf Builder Weed and Feed is a granule-form weed killer combined with fertilizer that targets dandelions and clover effectively. Its active ingredients, 2,4-D and Mecoprop-p, are well-known for controlling broadleaf weeds like dandelions, making it a solid choice if your main concern is those pesky weeds in your lawn. This product uses Weedgrip Technology, which helps it tackle visible weeds and those hidden in the soil, increasing its effectiveness. It covers a large area—up to 15,000 square feet—so it’s practical for medium to large lawns. The granules also feed your lawn, helping grass grow thicker and naturally shade out weeds over time.
One advantage is its satisfaction guarantee, suggesting confidence in weed control results. However, the product is not sold in some counties like Pinellas, FL, possibly due to local regulations on herbicide use. Application requires spreading granules evenly, and weed and feed products typically need a dry period after application to work best. Environmental impact is always a consideration with chemical weed killers; 2,4-D and Mecoprop-p can affect nearby plants if not used carefully, so following instructions is important to minimize harm.
If you want a weed control product that also nourishes your lawn and covers a big area easily, this is a dependable option, especially against dandelions. Just be mindful of local restrictions and application timing to achieve the best results.

Ortho GroundClear Weed & Grass Killer Refill - Kills Dandelions, Chickweed, Crabgrass, Moss and More in Patios, Landscapes, OMRI Listed Weed Spray Refill, 1 gal.
Ortho GroundClear Weed and Grass Killer Refill is a liquid spray designed to kill various stubborn weeds such as dandelions, chickweed, crabgrass, and moss in patios and landscape areas, but it is not meant for use on lawns or desirable grass. It works quickly, showing results within 15 minutes, and becomes rainproof after just 2 hours once dry. The refill bottle allows you to reuse the application wand from the original package for precise targeting, which helps avoid harming plants you want to keep.
This product is OMRI listed, meaning it's approved for organic use, which is a plus for those concerned about environmental impact. However, it’s important to apply it only when weeds are small, actively growing, and dry to ensure effectiveness. While it covers an average-sized area with one gallon, the product is heavier than some alternatives and is intended mainly for use on hard surfaces and landscaped beds rather than lawns themselves.
If you're looking to remove tough weeds from driveways, walkways, or garden beds—especially dandelions—this is a solid choice. Just avoid using it directly on your lawn grasses to prevent damage.
