10 Best Weed Killer For Dandelions In Lawn 2026 in the United States

Scotts Liquid Turf Builder with Plus 2 Weed Control is a liquid weed killer and fertilizer, designed to target a range of broadleaf weeds, including dandelions, while providing a nitrogen boost to your lawn. This ready-to-spray product is convenient for use when weeds are actively growing and covers a considerable area—6,000 sq. ft. for warm season lawns and 4,000 sq. ft. for cool season lawns.

It's suitable for various types of grasses like Bluegrass, Fescue, Ryegrass, and others listed, making it versatile for different lawn types. One of its strong points is the dual functionality of weed control and fertilization, simplifying lawn care routines by combining two tasks into one application. The active ingredient is nitrogen, which helps promote lawn growth while tackling weeds.

Scotts Liquid Turf Builder with Plus 2 Weed Control is a practical choice for those looking to manage broadleaf weeds and enhance their lawn's growth simultaneously. Users should consider potential environmental factors and rainfastness when choosing this product.

Scotts Turf Builder Weed & Feed5 is a granular product that combines weed control with lawn fertilization, making it a convenient choice for homeowners wanting to both kill weeds like dandelions and clover and strengthen their grass. It covers up to 4,000 square feet, which is suitable for medium-sized lawns. The product works best when applied to a wet lawn during mild weather (between 60°F and 90°F), helping it target actively growing weeds. It treats over 50 common lawn weeds, so it’s quite versatile. Scotts supports various grass types, including Bluegrass, Fescue, and Bermudagrass, which means it fits many typical lawn setups.

One of the benefits is that it not only kills weeds but also feeds the lawn to help thicken grass, which can reduce future weed growth. As a granular formula, it requires spreading evenly and watering in to activate, which might take some care to avoid patchy results. While it controls many weeds, it may not be as fast-acting or selective as liquid herbicides for tough dandelions.

Scotts Turf Builder Weed & Feed5 serves as a practical option for lawn owners seeking combined weed control and fertilization, especially if they want to maintain a healthy, thick lawn over time.
