Types of Invasive Bamboo - Alien Plant Control

As experts in alien plant control, specialising in invasive species across the UK, we offer highly qualified services at affordable prices. Bamboo, often planted for privacy and screening, can become a large nuisance affecting multiple properties. Here's a guide to prevalent species, running vs. clumping types, and why the distinction blurs in UK conditions.

Common Problematic Species

Myth? Running vs. Clumping Bamboo Varieties

In the UK's temperate climate, plant behaviour shifts dramatically from what would be expected in their natural habitat. Both types can be highly problematic once they reach approximately 7-10 years of maturity. We have also observed dwarf and bonsai species eventually starting aggressive spread once mature, not only larger heavier species.

Many clients ask us which type their bamboo is, and often, the answer is both running & clumping. Bamboos that are described as clumping varieties, may run in more mild winters or with fertile soils encouraging spread. Where as running types may slow in cold winters and frost prone areas, developing clumps of growth that are more resilient. It is also important to understand that bamboo is constantly sensing its conditions and climate, if the soil is too poor or the stand is too exposed, rhizomes can spread to establish new root balls in more desirable areas. Unfortunately, this tends to be neighbouring properties and land where more light, water and nutrients may be available.

It is also important to note that pruning and hedge trimming bamboo can encourage clumping types to run, as the plant's defence mechanism wants to spread and establish in safer locations where its not being cut back/grazed upon.

Problems with Bamboo Installation

Unfortunately, many garden centres and landscapers will recommend clumping bamboos as they do not run - this is entirely untrue for all species of clumping bamboo, there are not species that do not eventually spread with enough time. Many installation companies will not consider any form of containment, and we have found that the companies that do, only install to 30 cm maximum. We have observed rhizome escape in root barrier containment measuring 120 cm in depth. Bamboo, even when expertly contained, still requires monitoring to ensure effective results and to keep on top of the infestation that continues to become more mature and dense with time.
