In accordance with FGS Guidelines & Regulations, there are a number of prohibited species which should be dug up and removed, bagged and placed in the dumpster after removal.
As a general rule, when digging up/removing invasive plants, use a pitchfork or hand tool with long tines to loosen the dirt rather than a shovel—using a shovel may simply cut off roots/pieces which will easily grow back.

As a reminder, weed killer is not allowed in the Gardens! If you need help on technique, please contact the VP of the Park and your Area Directors.
