How to Propagate Bamboo from Culm Cuttings

Bamboo Propagation by Cuttings

Bamboo spreads via underground rhizomes and can become invasive if unmanaged. However, culm cuttings offer a controlled way to propagate new plants. Best from clumps under 3 years old.

Cutting and Planting Steps

Step 1: Select Source Material

Choose a clump less than 3 years old.

Step 2: Identify Nodes and Internodes

Nodes are swollen rings circling the culm; internodes are the sections between nodes.

Step 3: Make the First Cut

Cut ~½ inch below a node using sharp clippers for a clean cut. This piece is too long for a single cutting.

Step 4: Trim to Proper Length

Cut the top halfway between the 3rd and 4th nodes. The cutting now has 3 nodes, 2 full internodes, and a half-internode at the top.

Step 5: Plant Immediately

Plant in light, moist sandy soil with only the top node above ground. Seal the top cut with moist clay (don't cover the hollow). Keep soil consistently moist until new growth appears.

Rhizome barriers are essential when planting running bamboo in the ground.
