Due to its acidity, vinegar is a very powerful plant killer that can kill virtually any garden plant. Therefore, gardeners should make sure that vinegar does not come into contact with garden plants. They can pour vinegar directly onto plants growing in the patio or driveway, but should take more care when using it in the garden. To avoid accidentally splashing flowers and vegetables with vinegar, gardeners can add vinegar to a spray bottle and spray it directly on the weeds. For ideal results, they should avoid diluting the vinegar.
Weeds that are in very close proximity to garden plants can be a bit trickier. To kill these weeds without damaging other plants, gardeners can cut a soda bottle in half and place the top part over the plant. They can then spray the vinegar into the drinking spout. The bottle creates a barrier between the weed and nearby plants.
To kill stubborn weeds, gardeners can add one cup of salt to one gallon of white vinegar. A dash of dish soap can also help boost the weed killer's strength.Learn more about Gardening & Landscapes
