To plant clump-forming varieties, start by digging a hole that is twice the size of the rootball. Then, plant the bamboo so the rootball sits level with the surface. The whole can be filled back in with soil and watered in well.
With running bamboos, it’s ideal to grow them in containers so their growth is restricted. However, if you are growing in the ground it is beneficial to dig a trench and line it with impermeable material such as paving slabs so the roots of the bamboo can’t run and spread.
