3 Ingredient Homemade Weed Killer

Creating a Natural Vinegar Spray

Start with 2 c (400 mL) of white distilled vinegar.

Vinegar contains acetic acid, which effectively kills weeds. Keep in mind that vinegar is non-selective and will kill any living plant it touches, not just weeds. White vinegar can be used alone, or you can add additional ingredients to the vinegar to make an even stronger solution.

  • Avoid using vinegar on or near your lawn, since it will kill the grass.
  • Vinegar will raise the acidity of your soil. Before planting, test the pH of your soil and adjust it accordingly, if needed.
  • Use horticultural vinegar with 20% acetic acid for increased effectiveness between pavers or on patios. The extra acidity will affect the pH balance of your soil and other plants.

Add 2 to 3 tbsp (29 to 44 mL) of lemon juice concentrate, if desired.

Lemon juice contains high levels of citric acid and can be effective when used with white vinegar.

If you want to try it, simply mix the lemon juice in with your 2 c (400 mL) of white distilled vinegar.

Add 1 to 2 tsp (7 to 14 mL) of dish soap to kill particular plants.

Dish soap can be a helpful addition to vinegar when you’re dealing with weeds that have a waxy coating or a “hairy” surface, like dandelion and crabgrass.

The fuzzy exterior blocks the absorption of vinegar, but dish soap will penetrate the outer protective layer of the plant and help the mixture stick to the leaves.

  • You can use dish soap or dishwasher detergent in liquid or powder form.
  • Dish soap can be used in conjunction with a lemon-vinegar mixture, but a soap and vinegar solution will be very effective.

Mix 1 fl oz (30 mL) of rubbing alcohol into white vinegar.

Isopropyl alcohol can be very effective when mixed with white vinegar or even when used alone. You can also use cheap gin to achieve similar results.

Simply add the alcohol of your choice to the white vinegar and stir it thoroughly.

  • You can use alcohol, vinegar, and lemon juice together in one mixture, but a solution that strong may cause soil damage.

Dilute the vinegar solution 1:1 with water.

You can use the full-strength solution if your weed problem is severe, but this is typically too strong. A 50/50 mix diluted with water will be very effective on weeds without traumatizing the area where it’s used.

  • Full strength solutions may penetrate the soil and kill the roots of plants other than weeds. They can also disturb crucial microorganisms in the soil.

Pour the solution into a spray bottle and apply it to your weeds.

Use a funnel to transfer the solution to a spray bottle, then replace the nozzle tightly. Apply the solution to the weeds and monitor the results for 24 hours.

If needed, you can apply more solution, but you probably won’t need to.

  • Set the nozzle to “stream” rather than “spray” if the weeds are growing close to plants that you don’t want to kill.
  • Don’t forget — weed killer does not discriminate. It will kill any plant it comes in contact with, so use it carefully!

Killing Weeds with Other Household Products

Use rock salt or table salt as a weed killer.

Try this method only if you want to kill weeds in an area where you do not plan to grow anything for several years — perhaps around paving stones and in pavement cracks.

Salt kills the weeds by dehydrating them and absorbs them into the ground, preventing all plant growth. You can apply salt in one of two ways:

  • Dissolve 1/2 c (120 mL) salt into enough warm or hot water to fill your spray bottle.
  • Apply the salt dry. Simply sprinkle the salt on the weeds you want to kill. This works particularly well on garden paths and along lawn edgings.

Kill the weeds with boiling water.

Dump a large pot of boiling water on your weeds if there are no other plants close by.

Since boiling water kills the weeds by literally burning them, don’t use it around your other plants.

Boiling water can be very effective, especially on young weeds, and results are typically immediate.

  • You might have to repeat this several times over multiple days to sufficiently kill all the weeds.
  • Add 1 tbsp (15 g) of table salt to the boiling water to make an even stronger solution.

Be careful not to saturate the soil as it could damage the plants you want to keep.

  • Never use this solution to control weeds in a vegetable or flower garden; it will damage veggies and flowers.
