Bamboo can be both a beneficial and problematic addition to a garden, depending on how it is managed and the specific context. Let’s start with the pros and cons of having bamboo in your garden, and then discuss how to control or remove bamboo if it becomes invasive.
Pros of bamboo in the garden
Aesthetics: Bamboo can add a unique and exotic look to the garden with its tall, slender culms and lush green foliage.
Fast growth: Bamboo is one of the fastest-growing plants around, making it an excellent choice for creating privacy screens or natural barriers in a relatively short period.
Low maintenance: Once established, bamboo generally requires little maintenance, as it’s resilient and can tolerate various growing conditions.
Eco-friendly: Bamboo is a renewable resource that can be sustainably harvested for various uses, including bamboo construction, hammocks, crafts and even as a food source.
Erosion control: Its extensive root system helps prevent soil erosion and stabilises embankments, making it useful in landscaping projects.
Cons of bamboo in the garden
Invasive nature: Bamboo can be highly invasive if not contained properly. Running bamboo varieties can spread rapidly through rhizomes, taking over garden beds and neighbouring areas.
Space and height: Bamboo’s rapid growth can lead to overcrowding and overshadowing other plants, which may struggle to compete with it for light and nutrients.
Spreading challenges: Controlling the spread of bamboo requires dedicated efforts, and even with containment measures, it may still find ways to escape.
Root barrier maintenance: Installing a root barrier to control bamboo spread may work, but it requires periodic maintenance to prevent rhizomes from escaping.
Wildlife habitat: While bamboo can provide habitat and food for certain wildlife, it may also deter native species that prefer a more diverse ecosystem.
How to kill or control bamboo in the garden
If bamboo becomes invasive and poses a threat to the garden or surrounding areas, it’s essential to take appropriate measures to control or eradicate it effectively. Here are some methods to consider.
Digging and removing rhizomes: Digging out the entire root system, including the rhizomes, can be an effective way to remove bamboo. However, this process can be challenging and time-consuming, especially for mature stands.
Herbicides: Specific herbicides designed for bamboo control can be used, but they must be applied with caution to avoid harming other desirable plants and wildlife. Always follow the manufacturer’s instructions and take environmental precautions.
Repeated mowing or cutting: Regularly mowing or cutting down bamboo shoots will weaken the plant over time. However, this method requires consistency and may not completely eradicate the bamboo.
Solarisation: Covering the bamboo-infested area with a thick, light-blocking material (e.g. tarpaulin) and letting the sun heat up the soil can be effective in killing bamboo and its rhizomes.
Professional assistance: In severe cases, it may be best to seek the help of a professional landscaper or arborist experienced in dealing with bamboo invasions. You can see more about how to kill bamboo on EnvironetUK
Remember that killing or removing bamboo can be a challenging and ongoing process. Preventative measures, such as installing proper barriers when planting bamboo, can help avoid future problems with its spread. Additionally, choosing clumping bamboo varieties over running types can significantly reduce the risk of invasiveness.
