As spring unfolds in Minnesota, the Callery pear tree catches the eye with its vibrant white blossoms, yet it’s the pungent odor that might capture your nose. Known for its striking fall foliage and robust growth, the Callery pear is more than just a pretty face in the landscape—it's a growing problem.
Introduced to the U.S. in the early 1900s, the Callery pear quickly became a popular choice for urban and suburban landscapes due to its beautiful flowers and fast growth. Despite its appeal, the tree has shown a darker side. Its ability to cross-pollinate with other varieties has led to widespread seed production, contributing to its invasive nature. Once these seeds spread, they germinate and outcompete native flora, threatening local ecosystems.
Minnesota's response to the Callery pear’s aggressive spread includes a proactive phase-out. By 2026, the sale of Callery pears will be banned, as the tree will be officially listed as a Restricted Noxious Weed. This classification means it cannot be imported, sold, or transported within the state.
The structural integrity of Callery pear trees is weak, often leading to broken branches during storms, causing property damage or injuries. To combat the spread and mitigate damage, effective management strategies are essential. Removing mature, fruit-bearing trees is a critical first step to prevent further seed dispersal. For younger saplings, methods such as manual removal, foliar herbicide application, and a combination of cutting with herbicide treatment are recommended. It is also crucial to remove all root fragments to prevent regrowth.
For those dealing with an infestation, ongoing maintenance and regular scouting are recommended to keep the area clear of new growth. State resources, including the Minnesota Department of Natural Resources’ webpage on Callery pear, provide valuable information on control methods and herbicide options.
By understanding the characteristics and challenges posed by the Callery pear, Minnesotans can better manage this invasive species and help preserve the state’s natural landscapes. As we move forward, the focus remains on controlling this problematic tree and restoring balance to affected ecosystems.
