Buying Guide: Key Considerations For Selecting A Grass-Selective Herbicide
What weed species are you dealing with? Identify common grassy weeds like crabgrass, bermudagrass, foxtail, or quackgrass. Choose a product proven to control those species on the label.
Where will you apply it? If only around hardscapes, choose products with good drift control and edge-targeting capabilities (like AccuShot sprayers). For beds and borders, ensure your target plants are listed as safe on the label.
Are you treating lawns or non-lawn areas? This distinction matters. Many selective grass killers are designed for non-lawn use. Applying them to turf can lead to unsightly spots or damage.
How much area needs treatment? Large-bed aficionados may prefer concentrates offering economical coverage per square foot, while spot-treatment products suit smaller landscapes.
Safety and personal protection: Always follow label directions, wear protective gear if instructed, and avoid spray drift onto desirable plants or pollinator-friendly zones.
Application tips
- Apply on dry weather days with no rainfall forecast for the labeled window.
- Test on a small area first if you are unsure about plant tolerance.
- Avoid applying near roots of valuable trees or shallow-rooted ornamentals unless specified.
Maintenance considerations
- Reapply only as directed by the label and avoid over-application, which can harm non-target plants.
- Record where products were applied to track any follow-up treatments in the same season.
