Scotts Turf Builder Weed & Feed3 is a dual-purpose product that not only kills weeds like dandelions, clover, and over 50 other listed lawn weeds but also fertilizes your lawn to promote thick, healthy grass. This product is in granule form and contains active ingredients 2,4-D and Mecoprop, which are effective in weed control. It covers a substantial area of 5,000 sq. ft. per 14.29 lb. bag, making it suitable for medium to large lawns.

You should apply it to a wet lawn when weeds are actively growing and when the temperatures are between 60°F and 90°F for best results. The product can be used on various types of grass such as Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass. However, it's worth noting that it is not available in Florida, which may limit its availability for some users.

If you're looking for an all-in-one solution to manage weeds and nourish your lawn, Scotts Turf Builder Weed & Feed3 is a solid option, but be mindful of proper application to maximize its benefits.

The BioAdvanced 5 In 1 Weed and Feed is a granular lawn treatment that combines fertilizer and weed killer, designed to handle tough weeds like dandelions, crabgrass, clovers, and black medic. It works both by killing existing weeds and preventing new ones, which helps maintain a healthy, green lawn over time. Covering up to 10,000 square feet, it’s suitable for medium to large lawns and should be applied with a spreader to distribute the granules evenly. One of its strengths is showing visible results on crabgrass in about three days, indicating it acts fairly quickly against some weeds. The fertilizer component also helps strengthen your grass, keeping it greener for up to three months.

Since it is a granular formula, it’s less likely to wash away quickly compared to liquid sprays. This product is ideal for homeowners seeking a combined fertilizer and weed control solution that targets dandelions and other common lawn weeds, especially if they prefer a granular application. Users should be mindful of timing when applying the product to maximize effectiveness and consider environmental factors when choosing lawn treatments.

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.
