Ortho WeedClear Lawn Weed Killer Ready-To-Spray
Ortho’s Ready-To-Spray formula targets weeds within the lawn and works down to the root. It lists dandelion, clover, crabgrass, chickweed and foxtail among treated species. The product is designed to be broadcast over lawn grasses such as Bermudagrass, Buffalograss, fescues, Kentucky bluegrass, ryegrass, and zoysiagrass. A single application is described as fast-acting with visible results after treatment, depending on weather and weed pressure. Always apply on actively growing turf and avoid applying during extreme heat or drought conditions.
Ortho WeedClear Weed Killer for Lawns with Comfort Wand
This WeedClear option kills more than 250 listed weeds, including dandelion and clover, and is designed to spare most lawn grasses when used as directed. The Comfort Wand allows for targeted application, potentially reducing grass exposure to the active ingredients. The product supports a broad range of turf types—St. Augustinegrass (excluding Floratam), Bermudagrass, centipedegrass, zoysiagrass, buffalograss, bahiagrass, Kentucky bluegrass, ryegrass, and various fescues. Follow label directions for best results and avoid applying to stressed or dormant lawns.
Ortho WeedClear Lawn Weed Killer Concentrate
The concentrate version targets dandelion, clover, crabgrass and other listed weeds, killing them down to the root with a single application when used as directed. It is suitable for a wide range of lawns, including Bermudagrass, Buffalograss, fescues, Kentucky bluegrass, ryegrass, and zoysiagrass. Concentrates are often preferred for larger yards or when a more economical option is needed. As with all concentrates, accurate mixing and calibration are essential for effective control and safety of turf.
Roundup Weed and Grass Killer
Roundup Weed and Grass Killer delivers fast, broad-spectrum control that targets dandelions, crabgrass, clover and other broadleaf weeds. The product is designed for use in and around flower beds, trees and other landscape features, with a typical read-through allowing for subsequent planting after a specified interval. Its flexibility makes it a common choice for mixed-use areas; however, always ensure no direct spray reaches desirable plants, pollinator habitats, or water sources during application.
Scotts Turf Builder Weed & Feed3
Scotts Turf Builder Weed & Feed3 combines weed control with lawn fertilizer. It helps control a broad range of listed weeds, including dandelion and clover, while feeding the lawn to promote dense, weed-resistant growth. This option is suitable for actively growing lawns within the recommended temperature range (typically 60°F to 90°F) and should not be applied more than twice per year. It is best used when weeds are actively growing and the lawn is receptive to feeding, to maximize both weed suppression and turf health.
Buying Guide
Key considerations when selecting a dandelion and weed killer for grass include weed spectrum, turf safety, application method, and timing. The following perspectives help balance effectiveness with lawn health:
- Weed spectrum: If your lawn battles many weed species beyond dandelion and clover, choose products that list a broader weed menu (e.g., 250+ or 470+ weed types). Concentrates and professional-grade formulations often offer wider control.
- Turf safety: Read label directions to ensure compatibility with your grass type. Some products distinguish between warm-season and cool-season grasses and exclude certain grasses or stress conditions.
- Application method: Ready-to-spray and wand-based products are convenient for spot applications and smaller areas, while concentrates suit larger yards and may reduce per-use costs when mixed correctly.
- Timing and weather: Apply during active weed growth and favorable weather. Avoid mowing right before application, and do not spray during extreme heat, drought, rain, or windy conditions unless the label specifies otherwise.
- Safety and re-entry: Note any re-entry intervals for pets and children after spraying. Some products require waiting periods before returning to treated areas.
- Partner with lawn care: For lawns where fertilizer is also needed, consider weed-and-feed options that provide simultaneous weed control and nutrition, while monitoring nitrogen load to prevent over-fertilization.
In practice, select a product whose active ingredients target the most troublesome weeds on your property and cross-check compatibility with your grass type. For larger, multi-weed challenges, Roundup and Spectrum options offer broad coverage, while Ortho’s WeedClear line provides lawn-specific formulations with convenient application methods. Always follow the label for best results and environmental safety.
