How To Control Common Buckthorn: The Ultimate Guide

Introduction

Common buckthorn is an invasive shrub that is native to Europe and Asia. It was introduced to North America in the 1800s as an ornamental plant, but it has since escaped cultivation and become a serious problem. Buckthorn is now found throughout much of the United States and Canada, and it is considered one of the most invasive plants in North America.

Buckthorn poses a number of problems. It outcompetes native plants, reduces biodiversity, and contributes to erosion. It also produces berries that are poisonous to birds and mammals.

There are a number of ways to control common buckthorn. The best method for controlling buckthorn will vary depending on the size of the infestation and the location of the plants.

Non-Chemical Methods

There are a number of non-chemical methods that can be used to control common buckthorn. These methods are generally less expensive and less harmful to the environment than chemical methods.

• Cutting: One of the most effective ways to control buckthorn is to cut it down. When cutting buckthorn, it is important to cut the stump as close to the ground as possible. This will prevent the plant from resprouting.
• Pulling: Small buckthorn plants can be pulled out by hand. This is a good option for small infestations.
• Girdling: Girdling is a method of cutting the bark around the base of a plant, which will eventually kill the plant. This method is most effective for larger buckthorn plants.
• Mowing: Mowing can be used to control buckthorn in open areas. However, mowing will not kill the plant, and it may actually encourage resprouting.

Chemical Methods

Chemical methods can be used to control buckthorn, but they should only be used as a last resort. Chemical herbicides can be harmful to the environment, and they can also kill native plants.

• Glyphosate: Glyphosate is a non-selective herbicide that can be used to kill buckthorn. Glyphosate is most effective when applied to freshly cut stumps.
• Triclopyr: Triclopyr is a selective herbicide that can be used to kill buckthorn. Triclopyr is most effective when applied to the leaves of the plant.

Conclusion

Controlling common buckthorn is important for protecting native plants and wildlife. There are a number of methods that can be used to control buckthorn, and the best method for you will depend on the size of the infestation and the location of the plants.

If you are considering controlling buckthorn on your property, it is important to consult with a professional to get the best advice for your specific situation.
