Bamboo encompasses a number of different woody grasses that can grow from 4 to 6 feet tall to over 70 feet tall. Smaller varieties of bamboo can grow well as a container plant indoors under certain conditions. The main problem with growing bamboo indoors is humidity. Most varieties of bamboo need humid conditions for growth. However, there are a number of ways to increase humidity that can allow many smaller varieties of bamboo to thrive in indoor conditions.
Put a couple of inches of gravel in the bottom of a large pot that has a hole in the bottom to allow water to drain from the soil. The gravel will help improve drainage in the pot.
Fill the remainder of the pot to within 10 inches of the pot rim.
Lay the bamboo rhizomes eyes up on the soil.
Cover the rhizomes with 8 inches of soil. Leave a couple of inches of pot above the soil.
Place the pot in partial sun or strong indirect light.
Water the pot until water runs from the hole in the bottom of the pot.
Keep the soil moist, but not soaking wet, until the bamboo sprouts.
Slowly reduce water as the bamboo becomes established. Eventually, most varieties of bamboo will need a couple inches of water once or twice a week, depending on your climate.
