It targets more than 50 listed broadleaf weeds, including clover and dandelion, while providing nutrients to support new growth in spring.

Scotts Liquid Turf Builder with Plus 2 Weed Control
This ready-to-spray solution delivers both weed control and fertilizer in one application. It kills common broadleaf weeds such as dandelion, clover, and plantain while providing a nitrogen boost to accelerate greening. Apply when weeds are actively growing and temperatures are suitable, making it a quick option for mid-season weed management and lawn rejuvenation.
Scotts Turf Builder Weed & Feed3
Scotts Turf Builder Weed & Feed3 combines weed control with lawn feeding in a single application. It targets a broad list of weeds, including dandelion and clover, while promoting thicker, greener turf. Apply to a wet lawn during active weed growth and moderate temperatures (60°F–90°F) and avoid more than two applications per year to prevent over-fertilization.
Scotts Turf Builder Triple Action
Triple Action delivers a three-in-one approach: it kills existing listed weeds, prevents crabgrass for up to four months, and feeds the lawn to promote dense, green turf. It covers a broad spectrum of common lawn weeds and provides ongoing protection against new invaders, making it a solid all-in-one seasonal option for many home lawns.
Scotts Turf Builder Weed and Feed5

It’s suitable for active-growing lawns in moderate climates and follows the standard guideline of applying when weeds are visible and temperatures are in the 60°F to 90°F range. This product emphasizes weed suppression for long-term lawn health and reduced future weed pressure.
Buying Guide
Key factors to consider when choosing a weed killer and fertilizer for grass include lawn type, climate, and weed spectrum. Always read label directions for target weeds and safe application timing. Consider whether you need a one-step weed-and-feed or a two-step approach (weed control first, then fertilizer).
Seasonality matters: fall programs help prep for spring growth, while summer products target broadleaf and grassy weeds during peak growth. If you have Southern grasses like Bermudagrass or St. Augustine, look for products formulated for those varieties to maximize effectiveness and minimize injury to the turf.
Application method also affects results. Granular products require watering-in and may offer slower, longer-lasting control, while liquid formulas provide rapid results and easier coverage. For large lawns, consider products with broader coverage per box and simple spreader compatibility. Safety and environmental considerations include avoiding runoff, following label intervals, and storing products securely away from children and pets.
Finally, verify compatibility with existing lawn care practices, such as aeration schedules, overseeding plans, or the use of specific grass-type fertilizers. A balanced approach—weed control plus proper fertilization—tends to deliver the most consistent, healthy-looking lawns over time.
