How to Make a Homemade Weed KillerRecommended by my mom. This works extremely well, is non-toxic and there is very little chance of killing anything other than that to which it is directly applied.
Pour 1 gallon of white vinegar into a bucket. 5-percent household white vinegar is fine. It may take two or three days longer to kill the weeds with the lower concentration, but it does work.

Blend all thoroughly and then funnel the weed killer into a plastic spray bottle.
