Monitoring and rapid response
: Seedlings and shallow-rooted plants can be pulled when soil is moist. Dig small trees up or pull out, ensuring removal of the root system. If cutting is not possible, trees can be girdled during the spring and summer, by cutting through the bark all around the trunk, about 6 in above the ground. Large trees should be cut down and stumps treated with an appropriate systemic herbicide such as glyphosate of triclopyr.
