Quick buckthorn removal tips
Follow these quick tips for removing buckthorn (all of this information is further explained in the Managing Woodlands Buckthorn and Beyond presentation listed above):
- Don’t clear-cut buckthorn–gradual removal is best
- Do prioritize which buckthorn plants to remove first. Not all buckthorn is equal.
- Do give native species more room to grow by removing nearby buckthorn. Mark your native species with ribbon. In the fall, native species will turn color while buckthorn will remain green.
- Don’t confuse female buckthorn plants with chokecherry, black cherry and nannyberry plants, all of which bear black fruit.
- Do treat freshly cut buckthorn stumps when the temperature is above freezing.
- Do cut buckthorn when the ground is frozen, when working in areas where wildflowers grow.
When buckthorn is cut, what do you do with it? Here are some ideas:
- Place buckthorn logs flat on the ground to decompose. This is especially useful on slopes to slow water movement and prevent erosion.
- Make a buckthorn walking stick, trellis, arbor, fence or garden gate.
- Chip the brush (without berries) on site and use the chips for mulch.
- Bring the brush to the Minnetonka Public Works brush drop-off. While you are not required to separate the branches with black berries from the rest of the brush, it is appreciated.
