Growing bamboo in containers is a great way to keep it in check, since many forms of bamboo are invasive when planted in the ground. Also, container bound bamboo can be grown indoors, giving your house an exotic appeal. Care for container grown bamboo is easy, but there will come a time when you will have to transplant bamboo from one container to another to maintain the health of the plant.
Prepare a new pot for the bamboo. The pot should be wide enough to allow for 2 inches of space on all sides for the bamboo's rhizomes. Fill the bottom of the pot with rich potting soil.
If your bamboo is very tall, cut it to a manageable height, about 2 to 3 feet tall.
Loosen the soil around the bamboo you wish to transplant with a spade. Try not to disturb the roots. When the soil is loose enough, lift the bamboo from the pot.
Place the bamboo in the new pot and finish filling it with soil. Pat the soil down.
Water the bamboo well until the soil is moist but not soaking. Water the bamboo once or twice a week during its growing season and once every other week when it is dormant.
Keep tropical species of bamboo in full to partial sun or supplement with grow lights. Temperate varieties of bamboo have differing light requirements, from full sun to low light. Find out how much light your variety of bamboo needs and provide the proper amount.
Prune the bamboo regularly. Cut back unwanted culms (stems) at the soil. Cut off unwanted culm height above the node. Cut off any unsightly branches at the culm at any level.
