  • What kills weeds permanently?

  • In general, attacking and destroying the root of the plant is what kills weeds permanently. Using both natural and man-made weed killers like vinegar or Compare-N-Save work well to kill weeds on the surface. If the root of the plant survives however, the weeds will eventually grow back.

  • Do you need a chemical weed killer for lawns?

  • Weeds, such as crabgrass, dandelions and clover, can quickly overtake your turfgrass, changing the appearance and texture of your lawn. While good cultural practices are the best way to control weeds, sometimes a chemical weed killer for lawns may be necessary.

  • Is it safe to use herbicides on grass?

  • Several herbicide ingredients exist that do not harm grasses if used as directed. Spot-treating weeds with herbicides is not always safe for grass. Herbicide drifts can contaminate grasses, and the chemicals may stay in the soil long enough to damage the lawn. Choosing safer herbicides keeps weeds away and saves your grass from chemical burn-down.

  • Will fenoxaprop kill crabgrass?

  • The chemicals fenoxaprop and quinclorac can selectively kill grass weeds such as goosegrass or crabgrass. These are post-emergent herbicides that are usually used as spot treatments to kill the weeds growing in your lawn. Avoid mowing before applying the herbicide as you want the chemicals to contact as much of the weeds as possible.
