Compare-N-Save Concentrate Grass And Weed Killer – The Customer Favorite

As one of the top rated organic weed killers on the market, Compare-N-Save has skyrocketed to the top of the charts with their concentrate grass and weed killer.

This weed killer has been proven to be effective in clearing out both small and larger areas of unwanted weeds and grass. It’s main ingredient, glyphosate, is organic and has been deemed safe by the EPA for use on crops.

This concentrate mixes easily with water and is best applied on a sunny day with temperatures over 60°F with no rainfall forecasted for 24 hours.

However, this weed killer will kill all green plants so you will want to use it only on areas where you do not want grass to grow.

This can include driveways, along fences, around flower beds, and around fruit or vegetable gardens.

One gallon can cover up to 25,000 square feet and make up to 85 gallons of ready to use spray. Since Glyphosate is a post-emergent herbicide, it will not prevent new or future growth. Treated areas are able to be replanted in as little as 24 hours in ornamental areas.

This product not only kills at the surface, it kills to the root to completely abolish weeds.
