Agree with Lin. At this time of the year, they are on a slow down.
Oftentimes with my indoor tropical plants, seeing brown tips tells me either I am over or underwatering. So I have to adjust my watering style. But I try to wait for Spring before I do any repot, by that time, the plants are getting back to their usual growing vigor, temps getting more stable and light is getting longer. Dracaenas are not too choosy with soil, any good potting soil will work. I always add just a bit more perlite or pumice into the new media, to keep the media open. In containers, soil gets too compacted in time, so the roots suffer. Salt content in our tap water will also accumulate, hence the need to do a good flush of the soil, but wait for warmer temps to do this outdoors.
