Bamboo houseplants that grow in pebbles are commonly known as lucky bamboo. This popular plant, which isn't actually bamboo but rather a member of the Dracaena family, is fairly easy to care for. These plants thrive indoors because they do not crave direct sunlight. Indirect light, such as that from overhead fluorescent lights, is more than enough for lucky bamboo. Clean the rocks and vase that your stalk of lucky bamboo rests in once a week to keep the plant from developing a disease.
Place lucky bamboo plants in areas that get indirect sunlight, such as near a window or on top of the desk in your office. If the leaves fade to pale green and appear a bit droopy, the plant probably isn't getting enough light. Move it to a slightly brighter location.
Use bottled or filtered water in lucky bamboo vases. Treated tap water contains too much chlorine and fluoride and can damage the stalks and leaves. If you must use tap water, fill a small bowl with tap water and leave it uncovered in a cool, dry spot for 24 hours to allow the chlorine and fluoride to dissipate before watering your lucky bamboo.
Clean the vase and replace the water once a week. Tilt the vase slightly to the side and gently slide out the bamboo stalk, placing it on a folded paper towel. Dump the rocks into a fine mesh strainer, rinse them and pour them back into the vase. Insert the bamboo stalk back into the rocks and top off the vase with several inches of distilled or filtered water.
Fertilize the bamboo plant about once a month. Mix one part mild liquid houseplant fertilizer with 10 parts distilled or filtered water and pour several inches of the treated water into the vase in place of plain water.
Keep an eye on the plant's leaves. If they turn yellow or brown, this means that either chemicals in the water or the fertilizer has hurt the plant. Switch to an alternate type of water and discontinue use of the fertilizer solution.
