You can definately take side-shoots and get them to root. You can start them off either in soil or water, but for fast growing, go with the soil; just be sure to keep it watered! It's fairly simple; I've done it several times, an some of my shoots have gotten fairly tall! I'm not sure HOW tall LB can get, but some of mine are nearing two feet, are fairly straight, and a little top-heavy in some cases. Best of luck!

many seem to forget that dracaenas are trees. give them some time and proper care and they may get as big as those in this link, even bigger!

ewigerginkgo,
i am doing the same thing. I have a side shoot planted in soil and it has started to root and you said you have done this before and gotten your LB pretty big. About how long did it take until it got to around 2 ft.

I have a 60 inch lucky bamboo it is 17 years old
