Buying Guide: Key Purchase Considerations
- Lawn type and grass tolerance: Check label guidance to ensure compatibility with your grass (Bermudagrass, Kentucky bluegrass, fescues, ryegrass, etc.).
- Timing: Distinguish pre-emergent options (prevents seed germination) from post-emergent products (targets existing weeds). Some products offer both benefits with proper timing.
- Weed spectrum: If crabgrass is accompanied by dandelion, clover, or foxtail, choose a product with broad weed control or combine products as allowed by label directions.
- Application method: Consider ready-to-spray or concentrate forms. Ready-to-use products can simplify application for beginners, while concentrates may offer cost savings for larger lawns.
- Residual control and retreatment: Some products provide up to 30 days of residual control or season-long prevention; plan applications around the weed lifecycle and local climate.
- Environmental and safety considerations: Follow safety guidelines, keep pets and children away during application, and store products properly. Avoid mixing incompatible chemicals.
- Coverage area: Compare square footage coverage to choose a product that fits your lawn size and reduces waste.
- Re-entry and mowing: Note any re-entry interval after spraying and the recommended mowing schedule to maximize effectiveness.
