A recipe for vinegar weed killer is a mixture of vinegar, water, and sometimes other ingredients like salt or dish soap. It is a natural and effective way to kill weeds without using harsh chemicals. The acetic acid in vinegar works to break down the waxy coating on weeds, causing them to dehydrate and die.
Vinegar weed killers are relatively inexpensive and easy to make. They are also biodegradable and non-toxic, making them a safe choice for use around children and pets. However, it is important to note that vinegar can kill any plant it comes into contact with, so it is important to be careful when applying it.
