What Are Some Homemade Grass Killers?


Quick Answer

One effective grass killer is the use of 10 ounces of borax powder with 4 ounces of mildly warm water, SFGate notes, followed by 2.5 gallons of warm water when the powder dissolves properly. This concoction can treat an area of 1,000 square feet. One quart of vinegar, 4 ounces of lemon juice and 20 percent acetic acid also kills weeds and grass.

A more effective weed and grass killer, according to SFGate, is 1 tablespoon of dish soap, 1 tablespoon of 20 percent vinegar, 1 tablespoon of gin and a quart of water mixed together. This mixture kills the roots as well.

Garden Guide mentions a larger solution that requires one gallon of vinegar and chopped garlic cloves, allowing the mixture to sit in a small bucket for 24 hours. Get rid of the garlic cloves through a cheesecloth and add 1.25 cups of salt to the bucket.

Garden Guides discusses another vinegar solution by mixing it with salt. This solution kills weed and grass, but there is a chance of nothing growing in the sprayed area for the next few months. Bleach also kills grass and weeds directly, and gardeners can plant new items in the area in the next few days. Rubbing alcohol is another direct solution, and there is no need to add chemicals or dilute it in any way. The cheapest way of killing grass is to boil two cups of water and pour it over unwanted grass.
