If your lucky bamboo is in a state of good health, you will notice that its shape will change rather quickly. New shoots will grow straight instead of being coiled and intertwined as it was in the beginning. While you may have once found it attractive, the result will be a plant that does not have the proper balance.The good this is that lucky bamboo can be propagated easily.

Taking Cuttings

Taking healthy cuttings is the first step toward fixing the problem I typically do this after trimming the mother plant. Ideally, the cutting should have a minimum of one leaf joint; more is better. Trim any excess leaves that are covering the growth node. It is possible for lucky bamboo to be rooted bare or a hormone can be used. Normally, a hormone is not required since this type of plant roots readily. If you have tried a few times and things have not gone well, a hormone can be really helpful.

Rooting In Water

This is the preferred method of completing the process. Take all of your trimmings including any leaf joints, and place them in distilled water. You should notice reddish roots emerging from near the stalk’s bottom. It is important that you keep the water fresh and clean. After new roots have grown, you can place the plant in a vase with soil or decorative stones.

Rooting In Soil

It is also possible for lucky bamboo to root in soil. Gently push the trimmed stalk into a pot of soil. It is necessary for at least one root node to be placed beneath the surface level. Place the plant in a warm, moist environment if you want it to thrive.

When you are rooting lucky bamboo, you must keep in mind that new plants will not have the same look and growth patterns as the parent. It will be an attractive, solid plant with straight stems and green leaves, but it will not have the appearance of a lucky bamboo that was shaped and grown by a professional.
