But bamboo is most common in relatively pure stands between forest and farmland, on steep banks of streams and rivers, where the rhizomes bind erosion-prone soil and the culms are convenient for use in adjacent villages and farms. Most species appreciate warmth, humidity and partial shade. Unprotected south to west slopes should be avoided. Bamboos will grow in a wide variety of soils, but prefer slightly acid, well-drained sandy loam. Propagation and Management Bamboo is generally propagated by rhizome cuttings.
Rhizomes radiate from the base of a culm in the top two feet of soil.
They are best dug while dormant, in February, cleanly severed and protected from dehydration. After planting them to their original depth in a bed of compost mixed with soil, they should be well mulched, and watered regularly. New shoots are left alone for three years. Then, selective thinning will hasten the development of full-size culms. This process can take five to ten years, as the rhizome grows and is able to support larger shoots and culms.
