Lucky bamboo plants, which are not true bamboo but rather a type of houseplant, are generally grown in tall vases. Small pebbles or gravel are used to hold their long stalks upright in the container. Lucky bamboo is fairly simple to replant because it doesn't really need to be dug up like other plants. The plant just needs to be lifted from its rocks and placed in a new vase with pebbles and water. It is important to remove the plant gently to avoid damaging it.
Pour as much water as you can from the lucky bamboo plant's vase. Loosen the pebbles around the base of the plant with your fingers, then sweep them out of container into a trash can.
Tug gently on the base of the lucky bamboo plant (grasp it as low on the stalk as you can, given the depth and width of the vase.) Ease the plant out of the vase and place it on a few paper towels.
Fill a tall vase with a few inches of filtered or bottled water. Fluoride, which is found in most tap water, causes the leaves on lucky bamboo plants to turn yellow and die. Filtered and bottled water generally do not contain a high level of fluoride.
Slide the plant, root side down, into the vase and center it. Holding the plant in place with one hand, pour small pebbles or gravel into the vase. Fill in the space between the bamboo stalk and the vase walls, but stop adding the pebbles when the lucky bamboo is sufficiently supported. A few inches of pebbles should do the trick.
Place the lucky bamboo plant in an indoor area with bright, indirect light.
