Buying Guide
Key purchase considerations
- Weed spectrum: Look for products that list broadleaf weeds common to your area, plus any region-specific targets like crabgrass.
- Coverage and application method: Choose ready-to-spray for simplicity or concentrate if you need to scale coverage for larger lawns.
- Duration of protection: Most options offer up to six months; consider your local climate and mowing schedule when planning applications.
- Turf compatibility: Confirm compatibility with your grass type (Northern, Southern, St. Augustine, etc.) to maximize effectiveness and avoid turf stress.
- Preventive action: Prioritize products with preventive action to reduce recurrent weed pressure across the season.
- Rainfast window: A shorter rainproof period minimizes wash-off risk, but ensure proper drying and re-entry times after application.
Effectiveness and value comparisons
- Coverage vs. number of applications: Ready-to-spray options often require fewer handling steps, while concentrates may offer greater per-unit cost efficiency for larger properties.
- Combination benefits: Two-in-one formulas that kill existing weeds and prevent new ones can reduce total seasonal applications.
- Regional focus: Southern and Northern formulations tailor weed targets and timing to regional weed pressures and turf types.
Usage tips
- Apply during active weed growth for best results; avoid extreme heat or drought conditions.
- Wear protective clothing and follow label directions for mixing, application rates, and re-entry intervals.
- Watering: Some formulations require a rainfast period before watering; others may specify post-application watering to activate.
- Monitor lawn health after application and reapply according to label guidelines to maintain consistent protection.
