    Management

    • It can be weakened and ultimately controlled by vigilant, repeated clipping of the stalks throughout the growing season. This will starve the roots of nutrients and prevent plants from flowering or setting seed.
    • It is best not to attempt to dig or pull this plant up as it will stimulate reproduction by roots.
    • Herbicide can be used in the fall after repeated clippings have been done.
