Last spring I picked up a clumping bamboo from a plant sale. It has been doing fine in its location and recently sent up some new rhizomes. In the interest of creating more clumps, I removed these new canes and potted them. Most of the rhizomes had a tap root attached, but a couple only had lumps where the taproot was about to emerge. I potted them all in well draining, organic soil and put them in a sheltered spot where they get part sun. But I am curious as to how resilient these rhizomes tend to be? Will the ones without taproots continue to grow the nubs to form taproots? One rhizome had a two ft tall cane attachd that broke in half, will this one just leaf out and form more rhizomes or will it die off?
