Although most people associate bamboo with outdoor plantings, bamboo can grow very well in pots. Some bamboos can be grown hydroponically; you can maintain them by keeping them in diffuse light and adding water when needed. Other varieties growing in soil, however, require different treatment.
Place your potted bamboo where it will receive indirect light. Bamboo often grows under a taller canopy and doesn't like direct sun.
Water your bamboo enough to prevent the soil from drying out, usually every two or three days. Bamboos require moist but not soggy soil.
Mist your bamboo when you water if the air is dry. Bamboos like humidity.
Pick off leaves that turn brown or yellow. Brown or yellow leaves usually indicate excessive watering. Water less often, and the leaves should grow back green and healthy.
Re-pot the plant when you notice the roots pressing against the side of it. You can either move the entire bamboo to a larger pot or divide the roots and make two smaller potted bamboos.
