Scotts Turf Builder Weed and Feed3 – 5,000 Sq Ft
Scotts Turf Builder Weed & Feed3 combines weed killer and lawn fertilizer to strengthen your zoysia lawn while targeting over 50 listed weeds, including clover and dandelion. Designed for use when weeds are actively growing and temperatures range from 60°F to 90°F, this product aims to thicken the lawn to crowd out future weed growth. Application is limited to no more than twice per year, ensuring seasonality aligns with typical zoysia green-up cycles.
Listed features indicate an integrated approach: weed control plus lawn food to improve root development and turf density. It’s suitable for moderate-sized lawns seeking a balance of weed suppression and nutrient support. Follow label directions for proper application timing, water-in requirements, and safety considerations around pets and children.
Scotts Turf Builder Weed and Feed3 – 15,000 Sq Ft
This larger bag maintains Scotts’ weed-killer-plus-fertilizer approach, suitable for bigger zoysia lawns. It targets listed weeds like clover and dandelion while feeding to promote denser turf that resists future weed establishment. Application guidance emphasizes correct timing and avoiding over-application to prevent lawn stress. Follow label directions for watering and timing, and monitor for any local restrictions on fertilizer usage during peak growing seasons.
Scotts Turf Builder Bonus S Southern Weed & Feed2
Designed for southern climates, this weed killer plus fertilizer targets common southern weeds such as dollar weed, clover, and dandelion. The dual-action formula both kills existing weeds and feeds grass to encourage stronger, deeper roots, which helps zoysia compete with invading species. Application should be done on a dry lawn and watered in promptly after application to activate the product. Consider regional weed profiles when selecting this option for heat-tolerant lawns.
Scotts Liquid Turf Builder with Plus 2 Weed Control
This liquid formulation delivers quick-acting weed control along with fertilizer to kick-start greening. It targets several broadleaf weeds including dandelion, clover, ground ivy, and chickweed, and provides a nitrogen boost to promote faster lawn recovery. Liquid weed-and-feed products can be convenient for uniform coverage, but require careful measuring and timely application with the right sprayer settings to avoid over- or under-application.
Ortho WeedClear Weed Killer for Lawns
Ortho WeedClear provides broad weed kill for up to 16,000 sq ft, with the promise of results without harming established grass when used as directed. It targets over 250 common weeds, including dandelion, clover, and dollarweed, and emphasizes rapid visible results. As with all weed killers, follow label instructions to apply during active weed growth and avoid stressing the lawn through incorrect timing or weather conditions.
Buying Guide
Key purchase considerations for zoysia lawns include weed spectrum, lawn size, application method, and timing. If you prefer a single-package solution, granule formulas like the Scotts Weed & Feed options offer combined weed control and feeding, with coverage options for small to large lawns. For rapid results or uneven turf, liquid or ready-to-spray products such as the Scotts Liquid Turf Builder or Ortho WeedClear can provide quicker visible effects, but may require more precise application equipment and timing.
Seasonality matters: apply during active weed growth and when temperatures are within the recommended range. For zoysia, avoid applications during extreme heat or cold, and always water in granules or ensure sufficient moisture after spraying to activate the product. Consider regional weed profiles (dollar weed, clover, dandelion, etc.) when selecting a product to target the most relevant species. For larger or irregularly shaped lawns, select higher coverage products to minimize reapplication needs and maximize uniformity.
Environment and safety: read labels for pet and child restrictions, wear protective gear if advised, and follow any local environmental guidelines. If you have a mixed-species lawn or ornamental plantings nearby, ensure the product’s weed spectrum and tolerance align with surrounding vegetation. Finally, maintain mowing and irrigation practices that support a healthy zoysia stand, enabling better weed suppression over time.
