Buying Guide: Key Purchase Considerations
- Weed spectrum: Compare whether a product targets broadleaf weeds specifically or a wider mix, including grasses like crabgrass.
- Application format: Ready-to-spray versus granules; consider yard size, ease of use, and mixing requirements.
- Lawn type compatibility: Check labeled grasses (Bermudagrass, St. Augustine, Fescues, etc.) to avoid harming the lawn.
- Active ingredients and safety: Review active ingredients for selectivity, potential turf injury, and environmental impact.
- Seasonal considerations: Some formulas offer season-long protection or post-emergent control, while others focus on immediate results.
- Re-entry and mowing guidance: Note how long you should wait before re-entering treated areas or mowing after application.
- Urban and pet safety: Verify child- and pet-safe guidelines on the label and any required waiting periods.
- Maintenance plan: For persistent weed problems, a combination of post-emergent treatment and pre-emergent prevention may be most effective.
