Propagation of Bambusa chungii can be achieved through root divisions or by taking cuttings of young rhizomes. Root division is a common propagation technique. The clump is carefully dug up and divided into smaller sections, each with its own set of roots and culms.

Another method is taking cuttings from young rhizomes. This involves selecting healthy shoots and removing them from the parent plant. These cuttings can be planted in a well-draining soil mix and kept moist until they develop their own roots.

Both propagation techniques require attention to detail and patience but can result in successful establishment of new Bambusa chungii plants.


Bambusa chungii is a visually striking bamboo species suitable for warmer climates. Overall, Bambusa chungii adds beauty to gardens as a hedge, privacy screen, or windbreak option.
