Growing bamboo as a houseplant gives you a tall-growing plants that makes a bold statement in the home. Clumping bamboo varieties are most often grown in pots as the roots do not spread as quickly as running types, so they can be grown for several years before needing to be divided. You can propagate bamboo by cuttings. This grows a near clone of your existing plant and produces a mature bamboo much more quickly than seeding does.
Inspect the bamboo canes near the surface of the soil. Choose an outer cane that is ½ to 2 inches in diameter near the soil surface for your cutting.
Cut the cane off at the soil level with a sharp knife. Remove the top of the cane 1 inch above the nearest leaf node to the bottom. Continue cutting up the remaining cane above the leaf nodes, cutting each piece 4 to 4 ½ inches in length.
Fill a pot with a one part vermiculite and one part peat moss mixed together. Water the mixture until it is evenly moist throughout, but not soggy.
Plant the bamboo cuttings into the pot, pushing them into the soil until the leaf node is beneath the soil surface. Space the cuttings 3 inches apart in all directions.
Cover the pot with a plastic bag and place it in a warm room where it can receive bright, indirect sunlight. Water the soil in the pot if it begins to dry, or if condensation isn't appearing on the plastic bag.
Check the bamboo cuttings for rooting after six weeks. Gently tug on each cutting. If you feel resistance, it has rooted and can be transplanted to its own pot. If there is no resistance, continue to grow it in the cutting pot for an additional four to six weeks.
