Bamboos can sometimes have a thuggish reputation for aggressive underground root (rhizome) spreading, which can undermine surfaces. This rightly puts some people off growing some forms, but now with this new Bamboo Control Barrier, this need not be a worry any more. Made from tough, yet flexible plastic, simply surround the area you wish to contain the bamboo roots in with our purpose built barrier membrane, and it will control the spread of bamboo rhizomes perfectly. If inserted at a slight angle, it will even enhance growth, as the new rhizome shoot in Spring is persuaded upwards, and not outwards. Directs and controls bamboo growth into a specific area. Perfect for all spreading bamboos to protect driveway edges, fences, patios and from invasive spreading into neighbours\' areas. Easy to use whether planting a new bamboo, or encircling larger and established specimens to prevent further clump expansion.
