There was a clump of very untidy bamboo when we moved here 5 years ago which appeared to be just over 1m diameter. I hated it and the neighbours were very concerned that the bamboo had spread under their patio and started lifting the slabs.
We decided to launch a joint war on it from both sides.
We removed a huge root ball from the centre of the clump - about 1m diameter and about 18" deep. Further digging revealed several small smaller root balls (but all the same plant). The total area covered by the plant and runners was finally revealed to be about 3m x 3m.
We managed to dig out the root balls (very hard work) and as many runners as we could find (easy). Neighbours lifted their patio and did the same on that side. The whole area was left exposed for a season and we both either dug out new shoots / runners as they appeared or sprayed new shoots with glyphosate. Some of it had gone under paths so that had to be zapped with weedkiller.
We cleared the area in one season and were able to replant the next.
It's bloomin' hard work. No easy way other than heavy digging and you need to be really vigilant and zap any new shoots as they appear. Nobody would ever convince me to grow bamboo after that experience.
