How Do You Repot a Spiny Bamboo?
Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Spiny Bamboo?
Spiny Bamboo can be propagated through division, rhizome cuttings. Similar propagation techniques also apply to hedge bamboo plant care, which shares the same genus.
