You can use this grass and weed killer on driveways and in yards and gardens, as well as a plot prep product and even for stump regrowth management.

For an average yard, dilute 1 tablespoon of the product into a gallon of water to kill common weeds. It costs around $16 for 1 quart of the product.

Since this weed killer doesn’t act on soil, it’s safe to plant crops just days after spraying. It’s common for use in places where even turf is essential, like golf courses and pastures. Once sprayed, the weeds start to wither in hours and are dead in just three days.

Things to consider when shopping for the best weed killer spray 

When shopping for the best weed killer spray, it’s important to consider a few factors during the buying process. Many shoppers have different preferences regarding the chemical makeup of the weed killer. They also have different needs regarding which weeds to kill. Overall, you must consider four main factors:

  • Speed – Decide how quickly you need the herbicide to work. Check to find out if the product gives you the results you need in your desired timeline
  • Selectivity – There are products that kill all plant life or just broad-leaved weeds. Figure out if you need a preventative killer or a spray that just kills existing weeds
  • Chemical components – Different weed killers can use either organic, natural ingredients or synthetic chemicals
  • Location you’re using the product – Garden herbicide is specially made to treat soil after it’s been tilled. Its granules prevent new weed growth while leaving live plants alone

Frequently asked questions
