Understanding Vinegar as a Weed Killer

Vinegar contains acetic acid, which is a natural desiccant, meaning it dries out and kills the exposed parts of plants on contact. It works best on young, tender weeds but may not kill deeply rooted or perennial weeds completely.

Note: Household vinegar (5% acetic acid) works but can take multiple applications. For faster results, horticultural vinegar (20% acetic acid) is stronger but must be handled carefully.
