Buying Guide
- Weed type and spectrum: Choose a product with proven effectiveness against the weeds you see most often (dandelion, clover, crabgrass, etc.).
- Lawn type compatibility: Verify that the concentrate is labeled for your grass species (Bermudagrass, Kentucky Bluegrass, Fescues, Zoysia, etc.) and note any exclusions (e.g., Floratam St. Augustine).
- Concentration and dilution: Concentrates require mixing; follow label directions for water volumes, spray intervals, and application rates to avoid turf damage.
- Rainfastness and timing: Some products become rainfast within an hour; plan around rainfall and mowing schedules for best results.
- Selective vs non-selective: Selective products target broadleaf weeds in established lawns; non-selective formulas kill most plants and are best for driveways or edges rather than lawns.
- Environmental and pet safety: Review label guidance on application around children, pets, and water sources; store containers securely and dispose of empty containers properly.
- Application method: Consider spray patterns, nozzle type, and whether the product supports spot-treatments or whole-lawn applications.
- Long-term lawn health: Some products provide rapid weed kill but may affect regrowth; balance short-term control with ongoing lawn maintenance, including mowing height and fertilization.
Choosing the right concentrate involves weighing weed challenges against your lawn species, climate, and property size. By using products with proven field performance and adhering to label directions, you can achieve target weed suppression while preserving turf vitality.
