Removing unwanted bushes can be hassle, especially if you are short on time and energy. While pulling the pesky plants up yourself or hiring a professional is always an option, a more efficient, cost-effective method can be used: a salt and vinegar solution. Salt and vinegar can be combined to create a quick and easy plant killer, which will effectively dehydrate and destroy any undesired bushes in your yard.

Step 1

Mix 1 pound of salt with 1 gallon of 5 percent acetic acid white vinegar. Vinegar naturally consists of approximately 95 percent water and 5 percent acetic acid, which is an acid found in all living organisms. Acetic acid is effective as an herbicide, since the acidity damages and dries out leaves.

Step 2

Stir until the salt dissolves.

  • Removing unwanted bushes can be hassle, especially if you are short on time and energy.
  • Salt and vinegar can be combined to create a quick and easy plant killer, which will effectively dehydrate and destroy any undesired bushes in your yard.

Step 3

Mix 1 teaspoon of liquid soap into the solution. The soap will act as a surfactant, which lowers the surface tension of a liquid, thereby increasing the contact between the solution and the bush's leaves.

Step 4

Pour the solution into a spray bottle for easy application and wide coverage.

Step 5

Spray the foliage of the undesired bushes thoroughly until they are soaked. Vinegar is fast-acting; the acetic acid will quickly damage and dry out leaves. In addition, salt will decrease the available water and cause the bushes stress.

Step 6

Repeat the process once per day for three days, or until you see the leaves begin to brown.

  • Mix 1 teaspoon of liquid soap into the solution.
  • The soap will act as a surfactant, which lowers the surface tension of a liquid, thereby increasing the contact between the solution and the bush's leaves.

Tip

Wear protective gloves when handling the salt and vinegar solution.

Tip

For best results, use heated vinegar once a day for three days. The vinegar can be heated in your microwave at 10-second intervals until warm.

Warning

Keep solution away from eyes and face; it can cause burning and irritation.

Warning

Do not use on concrete; the solution will corrode the area.

Warning

Keep away from desired vegetation to avoid accidental plant death.
