Lucky bamboo plants are easy to propagate. The stalks possess the ability to put off their own roots when trimmed. This means one healthy plant can yield several new plants over its lifetime. This is a great way to spread the luck your plant has brought you to others. Bamboo grows quickly, so your new plant will establish itself and your old plant will heal in no time.
Examine your current plant to find the healthiest stalk. It may be your instinct to take your cuttings from the tallest plant, but you'll be better off choosing the one with the thickest, healthiest stalk with the deepest green color.
Prepare your rooting hormone. Rooting hormone comes in powder and liquid form. The liquid form must be diluted in water. The powdered hormone simply needs to be spread out on a piece of paper or in an old container. Be careful not to get any on eating surfaces because rooting hormone is toxic.
Choose a place on your plant from which to take a cutting. The piece needs to be at least four inches long and must start just above a node. The node is the area above one of the new growth rings. It's usually where leaves and stems emerge from the stem.
Use clean, sharp pruning shears to take a cutting from the top of your bamboo plant. Cut right above the node with one quick, clean cut. Avoid sawing or multiple cuts. You don't want a jagged edge.
Dip the bottom of your cutting in rooting hormone and set it aside. Prepare your new container by rinsing it out and adding two inches of gravel, rocks or marbles to the bottom. Press your cutting (rooting hormone end down) into the rocks so that it stands on its own. Add more rocks if necessary.
Add just enough filtered water to cover the rocks. Place the plant where it will receive indirect sunlight only. Change the water every 7 to 10 days. Your stalk will begin to put out roots in about a week. Be careful during water changes not to disturb those gentle roots.
