Title: Control of Smilax bona-nox (saw greenbrier)
Answered by: Joe Marcus
Smilax makes a thick, hardened root in which it stores water and nutrients. Hand pulling Cat-brier usually only breaks off the top-growth which the root quickly replaces.

Cutting new growth a few inches above the soil and painting the remaining stub with an herbicide labeled for that purpose is the most common control method.
