Bamboo is a fast-growing grass that has the physical structure of small trees. True bamboo houseplants are those that grow in soil, not standing water. There are over 1,200 varieties of bamboo, and most types can be grown in a container. Houseplant bamboo has similar requirements to other tropical type houseplants; however, it is best to verify the growing requirements for your variety for best results. It is rare for a bamboo plant to produce flowers, as they reduce the vigor in the plant and can cause the plant to die.
Plant indoor bamboo plants in well-draining potting soil. Place the bamboo in a potting container large enough so 2 or more inches are between the root ball and the edge of the container. A shorter container is better for the plant than a deep one.
Place the potted bamboo plant in a location that has a minimum of six hours of direct sunlight each day.
Water the bamboo plant once the top 2 to 3 inches of soil become dry. Water the plant to moisten the soil, but do not let the bamboo plant sit in water as this will kill the plant. Mist the bamboo several times a week with water to keep the humidity level high around the plant. Mist more frequently during the dry winter months.
Fertilize bamboo plants once a month with a 30-10-10 high-nitrogen, water-soluble fertilizer.
Repot the bamboo to a larger container once the root structure completely fills the current container area.
Train the bamboo to take a bonsai form once the root structure completely fills the container. Take the bamboo plant out of the container, remove 1/3 of the root structure by cutting the rhizomes with clippers and plant the bamboo into the same pot with fresh potting soil.
