When my dracenas get leggy, I just cut off the tops and stick them back in the ground. The original plant branches into two and looks nice fairly quickly. The tops also root quickly and fill in around the bottom of the originals.

Thanks solstice. I assume by leggy you mean what is happening to my larger plant. Enough leaves have fallen off or been removed by me to give me a large stalk. I have four stalks right now in a 12inch pot all of varying heights. The largest about four feet and the smallest about a foot. Different root depths also which I believe may be leading some to get more water and nutrients than others. Are you saying I can just hack off the bottom half of the largest one and put it right back into the soil like that? Is there a good time of the year to do this? I am in Chicago and it is still cold so they are getting a little less humidity in this dry air than they will in a month or two. If I keep the bottom half rooted you say I will get more growing up top on that part, even a splitting?
