Scotts Turf Builder WinterGuard Fall Weed & Feed3 is a dual-purpose product designed to both eliminate weeds and nourish your lawn during the fall. It has been formulated to target over 50 types of common lawn weeds, including dandelions and clover, making it versatile for varied weed problems. The product comes in granular form, making it easy to spread evenly across a lawn. A single 11.43 lb. bag can cover up to 4,000 square feet, which is convenient for medium-sized lawns.

For best results, it's recommended to apply when the lawn is moist, during active weed growth, and when temperatures are between 60°F and 90°F. This ensures that the product works effectively without harming the grass or the environment. The formulation also acts as a fertilizer, helping to prepare your lawn for a healthier spring growth. However, it's important to note that the product is best suited for specific lawn types such as Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass. If your lawn is composed of other grass types, this product might not be suitable.

Additionally, while it is effective in weed control, users should be cautious of its chemical composition, especially if they have pets or small children who frequently use the lawn. Always follow the safety guidelines provided. This product is a solid choice for homeowners looking for a combined fall weed control and fertilization solution, provided the lawn grass type matches those listed and safety guidelines are followed.

While its all-purpose nature and extensive coverage of 12,000 sq. ft. are notable strengths, its safety and environmental impact could be concerning due to the presence of active chemicals like Pendimethalin, 2, 4-D, and Dicamba. These ingredients might pose risks to pets, children, and the surrounding environment, so caution is advised during application.
