I also grow Dracaena's as house plants. I have 2 Dracaena sanderiana commonly called as lucky bamboo. I have one of them for about 5 years, and the other one is a little over 2 years. They do thrive in low light, and I have not put them in soil, just in those gel beads that hold water. From what I have observed, it does not like any fertilizer, still grows, albeit slow, which is fine with me, because I do not want to have a very lanky plant indoors. Here is a photo:
I also have Dracaena Marginata, and in low light, not too much watering required. Just keep it moist. One of them almost did not make it when I left it outdoors in winter,but luckily it is very forgiving once brought back in.
This one made a good comeback, almost killed it outdoors ooops!
This one has always been indoors and really thrives well.
Since the D.marginata is in soil, I also give it some liquid fertilizer. And it does help it grow better.
