Scotts Turf Builder Triple Action I, Weed Killer and Preventer Plus Lawn Fertilizer
Brand: Scotts
What it does: A three-in-one formula that kills listed weeds, prevents crabgrass for four months, and feeds to build thick, green lawns. It targets common lawn weeds including dandelion, clover, dollarweed, ground ivy, chickweed, plantain, henbit, and English daisy. The product also works as a preventive for listed grassy weeds while feeding the lawn for stronger turf growth.
How to use: Apply to a dry lawn and water as directed. Best results occur when weeds are actively growing and temperatures are within guidelines on the label. Notably, it does not kill existing crabgrass, but it prevents new crabgrass growth for several months, helping to reduce future weed pressure.
Strengths for Zoysia users include dual-action weed control and feeding properties, which can help establish a dense turf that crowds out future weeds. If your site has a history of annual weed flushes, this product’s preventive aspect can be particularly useful, as part of an integrated lawn care plan.

The label advises not applying more than twice per year.
How to use: Apply to a wet lawn during periods of weed activity and moderate temperatures, following the recommended rate per 1,000 sq ft. This product is suited for maintenance programs aiming to reduce weed pressure while sustaining lawn feed. For Zoysia, care should be taken to prevent over-application which can lead to nutrient burn or thatch buildup in damp seasons.
Overall, Weed & Feed3 offers a balance of weed management and nutrition. It’s a practical option for homeowners seeking a single-step approach to reduce weed competition while maintaining lawn vigor. For sensitive seasons or high-use zones, consider splitting applications or adjusting rates per the label.

It serves as a reliable weed-and-feed option designed to support warm-season lawns in southern climates.
How to use: Best applied during the growing season when weeds are actively growing and soil temperatures align with label directions. Because it targets Southern lawn varieties, it may be particularly effective for warm-season grasses common in southern regions. Follow rate guidelines and ensure even distribution to avoid spots with excessive product buildup.
For Zoysia lawns in warmer climates, this product can be a helpful seasonal choice to curb creeping weeds while providing essential nutrients. As with any weed-and-feed product, timing matters; apply when weeds are actively growing and temperatures are favorable for your region.

Buying guidance for Zoysia and similar grasses
- Timing matters: Apply weed killers when weeds are actively growing and temperatures are within the product’s recommended range. For pre-emergents, timing is tied to preventing weed seeds from germinating; for post-emergents, apply when weeds are visible and actively translocating nutrients.
- Seasonal alignment: Warm-season grasses like Zoysia respond well to products designed for Southern lawns during their peak growing season, but many products are labeled for year-round use in appropriate regions. Check local climate and label directions.
- Grass compatibility: Some products specify compatibility with Zoysia or include broad grass applicability. If you are unsure, start with smaller test areas or select products explicitly mentioning Zoysia or similar grasses in their guidance.
- Application rates: Avoid over-application, especially with weed-and-feed formulas. Over-fertilizing can lead to thatch buildup, burn, or increased susceptibility to pests and disease.
- Watering and mowing: Follow with irrigation if required by the label, and maintain proper mowing height for Zoysia to keep turf dense and competitive against weeds.
- Safety and storage: Store products in a cool, dry place and keep away from children and pets. Wear protective gear during application as directed by the label.
When selecting a product, consider whether you mainly need weed control, or a combined weed-and-feed solution, and how large your lawn area is. For Zoysia lawns, a strategy that emphasizes gradual, steady feeding combined with targeted weed control typically yields the best results without stressing the turf. If you’re first-time users, starting with a widely compatible option like a weed-and-feed product or a ready-to-use spray can provide a practical, low-effort approach to weed suppression and lawn nourishment.
In addition to product choices, pairing these treatments with regular mowing, proper irrigation, and seasonal aeration can further enhance Zoysia’s health. The combination of a robust feeding program and proactive weed management helps maintain dense turf, minimizes bare patches, and reduces weed pressure over time.
Buying Guide: Key Purchase Considerations
When choosing a fertilizer and weed killer product for Zoysia grass, these factors help ensure you select a plan that fits your lawn’s needs and regional conditions:
: Identify the most common weeds in your area (dandelions, clover, dollarweed, etc.) and choose products that reliably address those species. : Confirm that the product is labeled for use on Zoysia or is compatible with warm-season grasses similar to Zoysia. If in doubt, contact the manufacturer or consult local extension services. : Look for a balanced fertilizer that supports root development and overall vigor. Pay attention to nutrient ratios (N-P-K) and the presence of micronutrients if available. : Align product use with seasonal growth patterns. Pre-emergents help prevent weed seeds, while post-emergents target existing weeds. Temperature and moisture conditions on the label should guide timing. : Prefer products with lower environmental risk and avoid over-application. Consider long-term soil health and potential runoff in your landscape design. : Decide whether you prefer a single-step weed-and-feed solution or separate weed control and fertilizer applications. Having a plan helps maintain consistent turf quality throughout the growing season. : Follow all safety instructions, store products properly, and keep them away from children and pets. Use protective gear during handling as directed. : Larger lawns may benefit from concentrated granular formulas with spreader compatibility, whereas smaller areas can be effectively managed with ready-to-use liquids or sprays. Consider your preferred application method and equipment.
For best results, consider pairing weed-control products with a regular lawn care routine tailored to Zoysia. A proactive approach that combines seasonally appropriate fertilizer with targeted weed management can yield a healthier, more uniform lawn with fewer invasive weeds over time.
