Balsam Tree & Shrub Care
Aggressive and invasive species, such as Buckthorn [Rhamnus carthartica], can dominate a landscape if an available niche is made accessible.
A female Buckthorn produces hundreds of berries, which can amount to thousands of seeds. Removal has to be a multi-step process to prevent numerous new individuals from replacing the original.
Rhamnus cathartica, commonly known as Buckthorn, is extremely invasive to Minnesota. It was brought here roughly 200 years ago from Europe, where it was and continues to be used as an ornamental shrub. In the United States however, free from its natural constraints to growth, Buckthorn quickly invaded natural areas and began out-competing natural flora.
Although nurseries discontinued distribution of Buckthorn in the 1930's, Minnesota ecosystems continue to struggle with its persistence. Balsam Tree and Shrub Care cares about the native Minnesota ecosystem and landscape. That’s why we make a point to identify any Buckthorn we find to the property owner, so you have an opportunity to have it removed.
If your property has Buckthorn, it is extremely important that it be removed as soon as possible. Buckthorn can spread rapidly, regardless of whether the plants on your property are male or female. It outcompetes native plants for nutrients, light, and moisture, and ultimately reduces the diversity and health of other plants.
