Scotts Turf Builder Weed & Feed3 – 5,000 Sq Ft

Scotts Turf Builder Weed & Feed3 combines weed killer with lawn fertilizer, designed to address existing weeds while promoting a thicker, more competitive turf. The product targets a wide list of weeds, including clover and dandelion, helping to crowd out future invaders. It’s suited to lawns where temperatures range between 60°F and 90°F, with a caution against exceeding twice-per-year applications. This option is ideal for mid-sized lawns that require both weed control and fertilization in a single step.
Scotts Turf Builder Weed & Feed5 – 4,000 Sq Ft

This Scotts Weed & Feed5 formulation delivers weed control plus lawn nutrition to help thicken grass and deter future weed growth. It claims to control over 50 listed lawn weeds, including clover and dandelion, while feeding to promote a robust turf. Apply on a wet lawn when weeds are actively growing and temperatures fall within the 60–90°F window, and limit applications to no more than twice per year for best results.
Scotts Turf Builder Triple Action – 4,000 Sq Ft

Scotts Turf Builder Triple Action combines weed killing, weed prevention, and lawn fertilization in a single product. It targets a broad list of listed lawn weeds, including dandelion and clover, and adds crabgrass prevention for up to four months. The product is designed to keep existing weeds at bay while supporting thick, green growth. It’s suitable for lawns needing proactive weed control alongside ongoing nutrient support.
Scotts Turf Builder Halts Crabgrass Preventer – 5,000 Sq Ft

This product focuses on preventing crabgrass and other listed weeds before they invade, while providing lawn food for faster green-up after winter. It’s best applied in early spring on a dry lawn, prior to the third or fourth mowing, aligning with seasonal weed emergence patterns. The pre-emergent action helps protect established lawns from common grassy and broadleaf weeds when temps are rising toward regular summer levels.
Scotts Turf Builder Weed & Feed3 – 15,000 Sq Ft

This larger-coverage variant delivers the same weed killer plus lawn food concept for bigger properties, aiming to kill listed weeds while feeding to thicken the lawn and crowd out new invaders. The same 60–90°F active-growth window applies, and the guideline remains to limit applications to twice per year. It’s suitable for sizable yards that require extended weed suppression and sustained turf nutrition in a single treatment plan.
Buying Guide
- Weed spectrum: Most products target common broadleaf weeds like dandelion and clover. If your lawn has specific invaders (e.g., crabgrass, plantain), verify the product lists those weeds in its active ingredients or labeled weed list.
- Size and coverage: Choose a formula that fits your lawn size. Over- or under-application can reduce effectiveness and may be wasteful. Larger yards benefit from products with higher coverage per bag.
- Timing and temperature: Apply during the weed growth window and when daytime temps are typically 60–90°F. Avoid applying during extreme heat or drought, and follow label timing for pre-emergent vs. post-emergent products.
- Crabgrass prevention vs. control: If crabgrass is a recurring issue, consider a product that includes a pre-emergent crabgrass preventer in early spring, or use a separate program for prevention plus fertilization.
- Fertilization balance: Ensure the fertilizer aspect provides balanced nutrients to support lawn growth without encouraging excessive top growth that weeds may exploit.
- Environmental and safety notes: Read label instructions for pets, children, and runoff potential. Follow disposal guidelines and avoid applying near waterways or during rain events that could wash chemicals away.
- Compatibility with seeding: If you plan to overseed or reseed sections, check product compatibility, as some weed killers may temporarily inhibit seed germination or establishment.
- Application method: Granular formulations are typically spread with a broadcast spreader; adjust settings according to coverage. Watering requirements after application may vary by product.
- Long-term strategy: For persistent weed issues, integrate a lawn care routine that combines proper mowing height, irrigation, aeration, and periodic soil testing to maintain a dense, weed-resistant turf.
