Buckthorn Removal & Treatment
Buckthorn varieties have aggressively invaded our woodlands and wetlands. As they mature into tall shrubs and small trees, they cast dense shade preventing the establishment of native plants. Once established, buckthorn has the potential to spread very aggressively due to the production of large numbers of berries, each containing 3 to 4 seeds. In addition, the seeds can remain in the soil for up to 6 years before germinating. Removal of these plants is an important first step in controlling buckthorn in our landscapes and woodlands.
Remove all mature buckthorns from site. Treat all cut stumps larger than 1/4 inch in diameter with approved herbicide to prevent resprouting. Perform work June through February. Eliminate all seedlings by pulling, weed whipping, or foliar spraying with approved herbicide (spray from mid October through early November). Replant area with native plant material.
