Buying Guide
Key purchase considerations help you select the right weed and feed product for summer conditions:
- Lawn type and climate: Choose a formula suited to your grass species (cool-season vs warm-season) and local summer heat. Southern lawns may benefit from products designed for Bermudagrass or St. Augustinegrass, while cool-season lawns may respond better to other formulations.
- Weed targets: Identify the most common weeds in your area (dandelion, clover, crabgrass, plantain, purslane, etc.) and select a product that lists those weeds on the label for best results.
- Coverage and application rate: Compare coverage (sq ft) and bag size to estimate how many applications you can perform per season. Larger lawns may prefer granular formulas with broader coverage.
- Timing and temperature: Many weed-and-feed products work best when weeds are actively growing and temperatures are in a moderate range. Check label guidance for suitable windows and avoid applying during extreme heat or drought stress.
- Crabgrass prevention: If crabgrass is a persistent issue, select products with a proven crabgrass pre-emergent component to help curb reinfestation in summer and fall.
- Ease of use: Ready-to-spray options offer quickapps, while granular products require spreaders. Choose based on your comfort with application equipment and dispersion accuracy.
- Impact on established lawns: Some products emphasize lawn feeding to improve density, which can help suppress future weed growth by crowding out space for seedlings to establish.
- Safety and environmental considerations: Follow label directions, avoid over-application, and be mindful of runoff into water sources. Some products may be safer for pets after drying times specified on the label.
When in doubt, start with a product that explicitly lists weeds common in your region and follow with a second application only if the label permits. Maintaining proper mowing height, adequate irrigation, and timely fertilization will complement weed control efforts and help sustain a healthy lawn through summer.
