Control weeds in your yard with this simple homemade vinegar spray

Are you looking for a natural way to get rid of weeds that sprung up in your yard? Then look no further than your pantry since vinegar makes a perfect weed killer without any harmful herbicides. Acetic acid in vinegar destroys the plant cells and makes weeds wither, but there are a few things to know before you pour it straight onto those pesky problem areas. Keep reading, and we’ll walk you through how to use vinegar in your yard, plus some other alternatives for the most stubborn weeds.

Things You Should Know

  • Combine distilled white vinegar, salt, and liquid dish soap in your garden sprayer or a spray bottle. Use horticultural vinegar for additional strength.
  • Spray the leaves and stems of the weeds with your solution on a calm sunny day.
  • Reapply the vinegar solution every 2–3 days until the weeds die out.

Mix vinegar, salt, and dish soap in a sprayer.

  1. Adding salt and dish soap makes vinegar even more effective. Add 1 gallon (3.8 L) of distilled white vinegar that you have in your kitchen to your garden sprayer. Stir in 1 cup (273 g) of table salt and 1 tablespoon (15 ml) of dish soap until they’re thoroughly mixed. The added salt dries out the leaves even more, and dish soap helps the solution stick to the weeds.[1]
    • 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.

Spray the vinegar mixture on the weeds.

  1. Coat the leaves completely so the vinegar can soak in. Hold the spray nozzle as close as you can to the weeds you want to kill so you don’t accidentally spray other plants you want to keep. Simply pull the trigger on the sprayer or spray bottle to coat the weed with the solution. Continue spraying all of the weeds you want to get rid of.[3]
    • 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.

Reapply vinegar in a few days if the weeds don’t die.

5

Store the leftover solution in a labeled jug or bottle.

  1. You can keep and reuse vinegar as a weed killer each year. Empty your garden sprayer into a clean container with a lid and seal it tightly. Write “vinegar weed killer” or something similar on the side of the container so you don’t forget what’s inside. Store the container in a cool, dry place where you can easily access it whenever you need to spray weeds again.[5]
    • 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.

    The vinegar will kill the weeds you spray, but more weeds will likely grow back in a few weeks. You can reapply your vinegar mixture whenever you need to.
  • Question
    Can I spray shrubs for bugs with vinegar?

    No. Vinegar will damage the plant, not the bugs. To combat bugs, mix a couple teaspoons of neem oil and dishwashing liquid in a gallon of water and spray that on the infested plant. It may take a few applications to completely rid the plant of the infestation, especially if the solution gets washed off by rain or sprinklers. It's non-toxic to humans, but doesn't taste good, so you can spray it on ripening vegetables, but make sure you wash them before eating them.

Article SummaryX

To kill weeds with vinegar, first mix 1 gallon (4 liters) of white vinegar with 2 teaspoons (10 mL) of dish soap. The dish soap will help the vinegar stick to the weeds. Pour the mixture into a garden sprayer. Then, on a hot, sunny day, spray it directly on the leaves and bases of the weeds you want to kill. The sun will help the vinegar dry out and kill them. Wait 24 hours for the weeds to fully dry out, spraying a second time if necessary. If white vinegar doesn’t cut it, you can use 20% concentrated horticultural vinegar instead to make a more powerful mixture. Adding 2 cups (550 g) of table salt to your mixture will also make it stronger. For tips from our Horticulturist reviewer on how to use concentrated vinegar to kill stubborn weeds, scroll down.
