Cambridge, MA Invasive Plant Rules: Bamboo Restrictions (2026)

Massachusetts does not have a statewide bamboo ban, but the Massachusetts Prohibited Plant List (maintained by the Department of Agricultural Resources under MGL Chapter 128B) does not currently include bamboo species. However, running bamboo has become a significant concern in Middlesex County's suburban communities, where it can spread aggressively through rhizomes into neighboring properties. Several municipalities within Middlesex County have enacted local bamboo bylaws or regulations: The Town of Lexington passed a running bamboo bylaw prohibiting any monopodial (running) tropical or semi-tropical bamboo grasses that have encroached onto any property other than the property on which they were originally planted. Property owners must install and maintain a root barrier system (typically 30 inches deep, 60 mil HDPE) to prevent spread. Other Massachusetts towns (not necessarily in Middlesex County) have enacted similar bylaws, and the trend is growing. Even in municipalities without specific bamboo bylaws, running bamboo that spreads onto neighboring property can be addressed under Massachusetts common law nuisance principles and MGL Chapter 87 (which governs trees and vegetation on property boundaries). The Massachusetts Horticultural Society and UMass Extension recommend clumping bamboo species (Fargesia) as non-invasive alternatives to running bamboo in the New England climate. Running bamboo species like Phyllostachys aureosulcata (yellow groove bamboo) are cold-hardy and can be extremely aggressive in Massachusetts soil conditions.
