green woe

My Dracaena is not doing so well now. The smaller cane which I thought was reviving with new leaves, suddenly they all turned brown and wilted.

I just pulled the whole cane out, fearing it was dead and would spread rot. It had hardly any roots. I'm afraid I'm not watering it properly. Too often, probably. Hopefully the other cane stays alive, it still looks healthy enough, and has new little leaves sprouting in each crown.
