How to use vinegar as a weed killer.

How to use vinegar as a weed killer.Vinegar is a natural product, usually derived from grain, apples or grapes. It is distilled through a fermentation process. The vinegar you buy is typically labeled at 5% acidity. This means it contains 5% acetic acid, the active ingredient.

 Acetic acid is what makes vinegar a weed killer. Actually, it makes vinegar a plant killer. Acetic acid, from any source, will kill most vegetation because it draws all the moisture out of the leaf.Vinegar can also be used to promote growth of plants in drought regions. It is fast.

 Spraying full strength vinegar on a plant in full sun will often result in a withered, brown plant in only a few hours, for sensitive weeds, or by the next day in tougher plants.  This is because it is non-selective, meaning it might kill everything it touches.


This limits the usefulness of a vinegar weed killer, to the extent that you are able to control over-spray that would get on desirable plants.
