what is a natural grass killer
Vinegar is a common ingredient in homemade weed and grass killers and works well on annual weeds or young perennial weeds that have yet to become established. In order for the weed killer to be 80 to 100 percent effective, use 20 percent vinegar mix, according to the Oregon State Department of Agriculture.
Borax is also the main ingredient in a less-toxic homemade weed and grass killer that controls ground ivy and creeping charlie. Dissolve 10 ounces of the powder in 4 ounces of lukewarm water in a large bucket. After the borax dissolves completely, add 2 1/2 gallons of warm water and stir thoroughly.
