Fill a spray bottle if you don’t have a lot of weeds to kill. If you don’t have one, make your own with a glass bottle and spray nozzle. Standard vinegar usually has 5% acidity and works best for weeds that have appeared in the last 2 weeks. Use horticultural vinegar with 30–45% acidity to get rid of more established weeds. Just wear safety glasses and gardening gloves to protect yourself.
Avoid spraying weed killer when it’s supposed to rain since it could rinse off the vinegar before it gets rid of the plant.
Vinegar works best for weeds that are growing in sidewalks, driveways, or away from other plants since it can easily kill grass and other plants nearby. If you can, adjust the spray nozzle so it shoots a steady stream of the vinegar solution rather than a mist. A mist can easily blow away and get on other vegetation.
Vinegar may kill the leafy greens of perennial weeds, like dandelions or crabgrass, but it won’t reach the roots and plants may come back again the following season.
Be sure to clean your garden sprayer so the vinegar doesn’t cause any damage to the components. Avoid keeping horticultural vinegar in your kitchen so you don’t accidentally use it in your cooking.
If you aren’t able to pull the weeds by hand, dig them out with a trowel.
