Vinegar as Herbicide: Concentration Matters

Household vinegar (5% acetic acid) only kills very young weeds. Effective weed control requires 20% acetic acid, which is hazardous, strongly odorous, and rarely sold at garden centers. It burns foliage but doesn't kill roots, so weeds resprout.

Better Organic Approach

Pull weeds after a soaking rain when roots release easily. For persistent weeds, improve soil health and use mulch to suppress germination.
