We would strongly recommend installing a root barrier when you are planting bamboo. Bamboo plants tend to be very invasive after a few years of planting once they are established. The runners can be strong enough to push through paths and tarmac, and to undermine walls or other structures with shallow footings. The costs of repair can be high; it is far better to restrict and manage the roots from the offset.
Bamboo Root Barrier 420 is made from a strong and heavy geotextile which makes it sturdy yet flexible. It is waterproof, resistant to bacteria and most chemicals and is completely recyclable.
Bamboo Root Barrier 420 is UV resistant so it can be left partially above the soil surface; this makes it easy to prune away the undesired runners that some plants produce. It actually includes a 25 year warranty for preventing aggressive roots such as bamboo and reeds from growing through it!
Bamboo Root Barrier 420 is the strongest barrier on offer and stops the strongest of roots - bamboo, from damaging property or overtaking other plants and trees.
