Similar to the outdoor bamboo in appearance only, the bamboo grown as a houseplant is actually Dracaena, a member of the lily family native to Asia and Africa. This houseplant bamboo grows hydroponically and thrives in low light conditions. Plants can last for years; as they grow, their offshoots get longer. Gardeners can propagate a new indoor bamboo by taking cuttings from the original houseplant. Taking cuttings is quick and easy and can be done at any time of year.
Prepare a container for your lucky bamboo cutting. Fill the bottom of the container with a layer of gravel or pebbles at least 1-inch deep. Then fill the container with water. How much water you add depends on the size of your container, which is a matter of personal preference. Fill a large 12 or 16 oz. container partway or a smaller container with a 2 to 4 oz. capacity nearly to the brim.
Inspect your lucky bamboo before you take a cutting. You want to cut off a growing shoot, without cutting into the stalk. Select the largest growing shoot on your lucky bamboo. You can take multiple cuttings at a time.
Cut through the growing shoot with a sharp clean paring knife. Gently pull the shoot away from the main stalk if you're afraid you might cut the stalk. Pull the stalk away from the plant. Take any other cuttings in this manner.
Place the bamboo cutting in the prepared container of water. The cutting will develop roots over the next couple of weeks.
Continue to water the new and old bamboo plants. Top off the water level in your container to ensure a steady stream of fresh water, which keeps the plants' stress level down.
