Scotts WinterGuard Fall Weed & Feed3
Scotts Turf Builder WinterGuard Fall Weed & Feed3 combines weed control with fall lawn fertilization to prepare your lawn for spring. It targets more than 50 listed weeds, including clover and dandelion, while feeding the grass for strong growth when temperatures are between 60°F and 90°F. This product is designed for use on moist lawns and is suitable for fall applications that promote a healthier lawn next season.
Application guidance emphasizes weed-active periods and proper moisture. For best results, apply when weeds are actively growing and the lawn is moist, avoiding irrigation immediately after application to prevent washing off the product. The 4,000 sq ft coverage makes it a fit for standard residential lawns.
Scotts Weed and Feed5
Scotts Turf Builder Weed & Feed5 combines weed control with lawn fertilizer to help thicken grass and crowd out future weeds. It offers broad weed control (over 50 listed weeds) and should be applied to a wet lawn when weeds are actively growing and daytime temperatures range from 60°F to 90°F. Do not exceed two applications per year to avoid potential lawn stress.
This option is suitable for homeowners seeking a single-pass solution that both curbs existing weeds and promotes denser turf, improving resilience against future invasions by weeds or bare spots.
Scotts Triple Action Weed Killer and Fertilizer
Scotts Turf Builder Triple Action is a three-in-one formula that kills listed weeds, prevents crabgrass for up to four months, and feeds grass to build thick, green lawns. It targets a variety of common lawn weeds such as dandelion, clover, plantain, and chickweed, while offering ongoing protection against crabgrass and other grassy invaders. It is suitable for established lawns seeking sustained weed suppression and nutrient support.
Important usage note: while it prevents crabgrass, it will not kill existing crabgrass; plan accordingly if crabgrass is a current issue. The product is designed for 4,000 sq ft coverage and aligns with typical spring-fall weed management cycles.
BioAdvanced 5 in 1 Weed and Feed
BioAdvanced 5 in 1 Weed and Feed is a granule formulation designed to KILL tough listed weeds and PREVENT new ones. It also provides fertilizer to support lawn health and growth. The product emphasizes targeting broadleaf weeds with fast visible results (noted as typically within a few days) and helping maintain a robust lawn canopy to reduce weed establishment.
With its 9.6 lb bag, this option is practical for small-to-medium lawns and fits typical residential application patterns. For best results, follow label directions regarding active-growing periods and water requirements after application.
Scotts Weed & Feed3 (5,000 sq ft)
Scotts Turf Builder Weed & Feed3 is a weed killer plus lawn fertilizer designed to control listed weeds and feed grass at 5,000 sq ft coverage. It targets more than 50 listed weeds including clover and dandelion, while supporting lawn growth during favorable temperatures between 60°F and 90°F. It is suitable for homeowners who want a straightforward, single-pass lawn care product for larger yards.
The product stresses applying to a wet lawn when weeds are actively growing, ensuring that temperatures are within the recommended range for optimal weed control and nutrient uptake.
Spectracide Weed & Feed 20-0-0
Spectracide Weed & Feed 20-0-0 is a ready-to-spray formulation that combines weed control with lawn fertilization. It targets broadleaf weeds such as dandelion, chickweed, knotweed, plantain, and clover, while supplying nitrogen to feed the lawn. The ready-to-spray format offers quick application for established lawns that need immediate treatment for weed encroachment.
Users should apply when weeds are actively growing and avoid applying during extreme heat. The mix includes a balanced nitrogen contribution to support rapid turf recovery after weed kill events.
Buying Guide: Key Considerations For Selecting A Weed And Feed Product
- Weed spectrum: Compare which weeds are listed on the label and ensure the product targets your most troublesome species (dandelions, clovers, plantains, crabgrass, etc.).
- Release timing: Fall formulations help prep next spring, while spring or summer blends support rapid lawn establishment. Choose according to your climate and growing season.
- Coverage and bag size: Match product coverage (e.g., 4,000–5,000 sq ft) to your lawn size to avoid waste or under-application.
- Crabgrass prevention vs. control: Some products prevent crabgrass for months but do not kill existing crabgrass; plan for integrated weed management if crabgrass is present.
- Nitrogen content and feeding needs: Higher nitrogen helps quick green-up but may risk rapid growth and thatch if overapplied. Follow label guidance for annual limits.
- Moisture and application conditions: Apply to a moist lawn within the recommended temperature window. Avoid applying during extreme heat or drought conditions where possible.
- Re-entry and safety: Adhere to safety precautions on the bag and rinse-off guidelines, especially in households with children or pets.
- Environmental considerations: Select formulations with edge-of-lawn safety in mind and avoid runoff into nearby waterways by following application rates and watering instructions.
The selection above provides a range of options from well-known brands. For larger lawns or specific weed challenges, the Triple Action or 5-in-1 formulations may offer broader benefits, while ready-to-spray Spectracide provides a quick, convenient approach. Always consult product labels to confirm suitability for your yard’s grass type and regional growing conditions.
