Tips for Using Vinegar to Kill Weeds
- Apply on sunny days: Sunlight helps dry out weeds faster.
- Target weeds only: Vinegar is non-selective, so avoid spraying desirable plants.
- Reapply if needed: Stubborn weeds may require multiple treatments.
- Use protective gear: Wear gloves and goggles when using strong horticultural vinegar.
- Test small areas first: Check that vinegar won’t harm nearby plants before wide use.
Does Vinegar Kill Weeds Permanently?
Vinegar kills small or young weeds effectively, but perennial weeds with deep roots often need repeated treatments to weaken their roots and prevent regrowth.
Salt-based recipes can linger in soil and harm future plants, so avoid using those near areas where you want to grow other plants.
