Homemade vinegar & salt weed killer

Updated March 16, 2017

If you are a gardener, you probably strive to keep you garden looking pristine and free of weeds. Weeds, unfortunately, are pesky plants and seem to find ways to escape your efforts to eradicate them. While commercial, chemical, weed killers are available, think about using a more environmentally friendly approach. You can make a homemade vinegar and salt weed killer that should keep those intruders at bay.

Homemade Vinegar and Salt Weed Killer

According to thisgardenisillegal.com (see References), vinegar makes a great weed killer because of the acetic acid. The acid in the vinegar works to kill the leaves of the plant by removing moisture. Unfortunately, the vinegar does not kill the root of the weed. The reason, according to the University of Wisconsin, is that the vinegar available at the grocery store is only about 5 per cent acetic acid. Fortunately, adding another ingredient to the vinegar will help totally kill the weed.

The other ingredient in this weed killer is salt. Salt, however, can be problematic to use as a weed killer because (in large doses) it renders the soil around the plant unsuitable for future growth. Salt, therefore, will get to the root of the matter (so to speak) and kill the weed completely. It just needs to be used sparingly.

To make this homemade weed killer, you will need 1 quart of water (which will help to dilute the effects of the salt on the soil), 5 tablespoons of vinegar and 2 tablespoons of salt. This recipe comes courtesy of recipezaar.com (see Resources). According to this site, first, boil the quart of water. Next, add the salt and the vinegar to the water. Finally, while the mixture is still hot, pour the liquid over the weed.
