Monitoring and rapid response
: Removal of plants by hand-pulling or use a 4-prong spading fork when the soil is moist. Branches and berries should be bagged but the remaining plant material can be left to compost. Sites can be burned or mowed. Also can be effectively controlled using any of several readily available general use herbicides such as glyphosate, triclopyr, or metsulfuron-methyl.
