Scotts Turf Builder Weed and Feed5

Features include weed killing for clover and dandelion combined with lawn feeding to thicken turf. Best for lawns where active weed growth coincides with moderate temperatures (60–90°F). Apply no more than twice per year. Do not use on St. Augustinegrass Floratam and a few other warm-season grasses. Suitable for areas up to 4,000 sq. ft. This choice is ideal for homeowners dealing with visible broadleaf weeds in cool-season or transition-zone lawns seeking a single-step treatment.
Scotts Turf Builder Weed and Feed 3

This product emphasizes stronger dandelion and clover control with a 5,000 sq. ft. coverage. Its Weedgrip Technology helps grip both visible and hidden weeds for effective removal. Choose this if you have a larger lawn with persistent broadleaf weeds and want confidence in ongoing control across a full season. Best for medium-to-large lawns seeking a balanced mix of weed control and feeding.
Scotts Liquid Turf Builder with Plus 2 Weed Control

This ready-to-spray solution provides a quick nitrogen boost while delivering weed control through a hose-end applicator. It is best for homeowners who want a fast, easy-to-apply option and have weeds actively growing. It targets many common broadleaf species, making it a good fit for smaller to medium lawns that benefit from rapid nutrient uptake and weed suppression in a single pass. Caution: ensure proper dilution and scouting for sensitive turf types before use.
Spectracide Weed & Feed 20-0-0

Dual-action formula kills major broadleaf weeds while feeding the lawn with 20% nitrogen. It targets weeds such as dandelion, chickweed, clover, plantain, and more. Best for homeowners who want a reliable, easy-to-use option with clear weed targets and a consistent feeding effect. A caveat is to follow labeled restrictions for sensitive regions and ensure even coverage to prevent streaking on lawns with uneven terrain.
BioAdvanced 5-in-1 Weed and Feed

Offers 5-in-1 action: kills listed weeds, prevents new weeds for up to six months, feeds, greens, and strengthens the lawn, and controls crabgrass via a robust four-weed killer mix. Best for lawns with heavy weed pressure and crabgrass risk. Use in spring or early summer; apply even if existing crabgrass has already emerged. Limitations include a longer prevention window and the potential need for reapplication in later seasons to maintain the barrier.
Scotts Turf Builder Triple Action

Three-in-one formula combines weed control, crabgrass prevention, and lawn feeding to build thick, green turf. Suitable for multiple common lawn grasses. Best for homeowners who want a single product to address both weed issues and crabgrass risk while promoting healthy growth. A limitation is the restricted coverage depending on the exact product variant; verify square footage on the bag to ensure adequate spread for large yards.
Scotts Turf Builder Triple Action (12,000 sq. ft.)

A larger-area variant of the Triple Action program, designed to cover up to 12,000 sq. ft. It provides 3-in-1 benefits: weed control, crabgrass prevention, and fertilizer. Best for expansive lawns seeking a consolidated approach to weed management and turf nutrition. Consider this option if your yard is more than 5,000 sq. ft. to avoid reapplications due to insufficient coverage.
Ortho WeedClear Lawn Weed Killer Ready-To-Spray

Ortho WeedClear uses a hose-end applicator for quick, one-pass weed elimination. It targets dandelions, clover, crabgrass, and other common lawn weeds and covers up to 5,000 sq. ft. Best for homeowners seeking a fast, convenient solution with minimal setup. Limitation: efficacy depends on proper hose-end operation and uniform application across uneven terrain.
Buying Guide: Key Considerations for Weed Killer Lawn Feeds
- Lawn type compatibility: Some formulas are not suitable for certain warm-season grasses. Always check label recommendations for St. Augustinegrass, Floratam, Bentgrass, and other sensitive varieties.
- Weed spectrum: Identify target weeds (dandelion, clover, crabgrass, chickweed, etc.) and choose a product that lists those species on the label.
- Coverage area: Match product coverage to your lawn size. Large yards may require higher-volume options or multiple bags.
- Longevity and reapplication: Some products provide extended weed prevention, while others require more frequent applications. Plan for seasonal timing and reapplication intervals.
- Application method: Convenience varies from hose-end sprayers to granular spreaders. Select a method that aligns with your routine and lawn layout.
- Safety and restrictions: Follow label directions, observe pet and child guidelines, and avoid application before heavy rain or extreme heat.
