Controlling Kudzu Vine: Best way to kill Kudzu…

Kudzu Vine was introduced to the United States in the early 1900s as an erosion control measure. However, it quickly escaped cultivation and became a major invasive species in the southeastern United States. Kudzu threatens native ecosystems because it can outcompete native plants for light, water, and nutrients. Once regarded as a wonder plant, this invasive vine is now a pest for many homeowners in the southeastern United States. But do not worry, With the right knowledge and strategy, you can defeat kudzu and recover your green haven.

What is Kudzu

Kudzu Vine (Pueraria montana) is a perennial vine native to East Asia, but invasive in many parts of the world, primarily North America. It is a fast-growing, climbing vine that can suffocate other plants and trees. Kudzu belongs to the pea family (Fabaceae) and is related to soybeans and peanuts. Kudzu Vine is known for its aggressive growth habits. Kudzu vines can grow up to 100 feet (30 meters) in a single season and smother trees, buildings, and other vegetation.

Methods for Kudzu Control


This involves repeated mowing or cutting the vines close to the ground, ideally every week during the growing season for 2-3 years. It harms the plant by preventing it from producing leaves and replenishing its energy reserves. Useful for small infestations, but very labour-intensive.


This eco-friendly approach utilizes goats and other livestock known to enjoy kudzu. Goats are particularly effective grazers because they can climb and consume large amounts of kudzu vines. However, proper management is essential. Overgrazing can damage the land, and kudzu can regenerate if not continuously grazed. Grazing is best suited for areas where you can manage livestock and may need to be combined with other control methods for long-term success.


Herbicides containing glyphosate are the most common choice for kudzu control due to their effectiveness. However, they are non-selective, which means they can harm both desirable and undesirable plants. Fortunately, selective herbicide options are available for targeted control near valuable vegetation. The application method also plays a crucial role.

  • Basal bark treatment: for instance, involves applying herbicide directly to the base of vines climbing trees, minimizing damage to the tree itself.
  • Foliar spray: Foliar sprays target the leaves but require careful application to avoid harming nearby plants. Follow the herbicide label instructions precisely for safety and optimal results.
  • Additional tips:
    1. The best method depends on factors like infestation size, budget, and environmental concerns.
    2. For large areas, a combination of methods might be most effective.

How to get rid of Kudzu vine

Kudzu is now considered to be a noxious weed in many parts of the country. Kudzu can also reproduce vegetatively by fragmentation, which means even small pieces of the vine can sprout new plants. It thrives in warm climates and is not affected by poor soil conditions. It is a perennial vine, with deep roots that are nearly impossible to dig up. The best option is to mow or cut it back, then spray it with a chemical herbicide. also here are some methods you can try

  • Natural Kudzu Killer Spray: Mix white vinegar, salt, and a squirt of dish soap in a bucket. Stir until the salt dissolves, then pour the solution into a garden sprayer. On a hot day, thoroughly drench the kudzu vines with the spray, ensuring all parts of the plant are saturated. Repeat weekly until the vine is dead.
  • Smothering Technique: Cover the kudzu with plastic tarps, securing them with weights. This method deprives the plants of sunlight and air, eventually killing them
  • Herbicide Treatment: Use a herbicide containing triclopyr or glyphosate for a more aggressive approach. Apply the herbicide during the vine’s active growth period, usually in the spring or early summer. Always wear protective gear when handling herbicides and be cautious not to harm beneficial plants nearby.

Additional Tips

  • Consult your local Cooperative Extension Service for specific recommendations on kudzu control methods best suited for your area and situation. They can advise on herbicide choices and regulations.
  • Consider a combination of methods for optimal results. Weakening the vine mechanically can make herbicide application more effective.
