What's
Wrong with Buckthorn?
- Competes
with native plants for light, space, and nutrients.
- Seeds
may persist in the soil for up to 6 years before germinating.
- Has
chemicals in its roots, leaves, and fruit that inhibit the growth
of other plants.
- Are
vigorous trees that are difficult to kill, even with herbicides.
- Creates
a monoculture as it invades an area, decreasing diversity of
plant communities and wildlife habitat.
Steps
to Removing Buckthorn
- Remove
the medium and large buckthorn trees. Stumps must be ground
out or treated chemically. Fall is an optimum time to begin
this phase.
- Pull
or spray smaller seedlings.
- Once
removed, there will be a flush of new growth. Pull or spray
new seedlings. This phase could last several years.
- Replanting
may be necessary if the buckthorn has displaced native plants
in the area. Established native plants will make it more difficult
for buckthorn to reinvade making them a crucial part of the
restoration process.
