Bamboo can successfully be grown in New York, but doing so requires careful planning and selection to overcome two primary challenges. The state’s climate, which spans USDA Hardiness Zones 4 through 7, demands species that can withstand cold winters. Furthermore, the plant’s naturally aggressive growth habit necessitates proactive management to prevent it from spreading unchecked. Cultivating bamboo in this region is entirely possible, yet it depends on diligence in choosing the correct variety and implementing appropriate containment methods from the start.
Choosing Cold-Hardy Species
The survival of bamboo in New York’s variable climate depends heavily on selecting species with sufficient cold tolerance. Bamboo is classified into two main types based on its underground root structure: running and clumping. Running bamboo, belonging mostly to the genus Phyllostachys, spreads rapidly via long, slender rhizomes, while clumping bamboo, often from the genus Fargesia, expands slowly from short, thick rhizomes.
For the coldest parts of the state (Zone 4/5), clumping varieties are the most reliable choice, as many can survive temperatures down to -20°F. Specific species like Fargesia murieliae (Umbrella Bamboo) and Fargesia nitida are highly recommended because of their exceptional hardiness and non-invasive growth pattern. These plants form dense, contained clumps.
If a larger screen is desired, some running bamboos can tolerate the cold, but they must be managed strictly. Phyllostachys bissetii is a good example, known to be hardy to approximately -20°F. While the above-ground canes and leaves of even cold-hardy varieties may suffer significant damage, known as “leaf burn” or “top-kill,” the underground rhizome system often survives.
Winter damage often presents as the leaves turning tan and dropping off, or the canes themselves dying back to the ground. The plant is not dead in these cases; the rhizomes remain viable, and new shoots will emerge in the spring. To aid in winter survival, a thick layer of mulch helps insulate the root system from the coldest temperatures.
Managing Aggressive Growth
For any running bamboo variety planted in New York, the aggressive nature of its underground rhizomes requires containment to prevent invasive spread. The most effective method involves installing a physical rhizome barrier. This barrier should be made of High-Density Polyethylene (HDPE) plastic, typically 60 to 80 mil thick, which provides sufficient resistance to penetration.
The barrier must be installed vertically into a trench surrounding the planting area to a depth of at least 30 inches. Crucially, the top edge of the barrier needs to remain exposed, rising one to two inches above the soil level.
Leaving the barrier slightly above the ground allows for easy monitoring of rhizomes that attempt to “hop” over the barrier. Any rhizomes spotted growing over the top edge must be pruned back immediately to maintain containment. For large areas, an alternative management technique involves installing a barrier only on the side facing a property line or structure and regularly mowing the ground on the uncontained side.
Growing bamboo in containers or raised beds offers a guaranteed containment solution. However, containerized bamboo roots are much more susceptible to freezing temperatures because they lack the insulation of the earth. For winter protection, containers should be insulated with materials like bubble wrap or burlap, or placed in a sheltered, unheated location such as a garage.
Local Regulations and Legal Requirements
Before planting any bamboo in New York, particularly running varieties, it is necessary to investigate local zoning and municipal ordinances. While New York State has restricted the planting of running bamboo since 2015 due to its invasive characteristics, many municipalities have enacted more specific, mandatory regulations.
Many local governments, particularly in suburban areas, have specific laws concerning running bamboo. Some areas require property owners to install and maintain barriers to contain their bamboo, while others have prohibited the planting of running bamboo entirely and require a permit for clumping varieties.
Common legal mandates often specify the exact requirements for a containment barrier, sometimes requiring the 30-inch depth barrier if the bamboo is planted near a property line. Property owners are legally liable for any damage or encroachment that their bamboo causes to a neighbor’s property. The responsibility for all removal and containment costs falls upon the planting homeowner.
Homeowners must contact their local town or village planning or zoning department to confirm the specific requirements in their area. Failure to comply with these ordinances can result in fines for each day the violation continues. Since the definition of running bamboo in local laws often includes a presumption of guilt if the plant is found on a neighbor’s land, adhering to all barrier specifications is mandatory to avoid legal issues.
