Question
I have a Dracaena marginata it pretty young, has two big stems and each of them has like 3 smaller stems coming out of it, today I noticed that the bottom of one of the big stems is looking weird the bark looks like it's loose or coming off, so I dug into the soil a bit to check if the stem is rotting and when I reached some roots they look very brown and mushy so I know my plant has root rot so I realized that I have been overwatering it. So I took out the plant  from the pot, I got rid of the brown soft roots as best as I could  and replanted the plant in the new soil. I'm still afraid that my plant might not make it, it looks fine when you look at it but there was not many healthy looking roots I only seen a couple and I couldn't get rid of all the brown soft roots because some of the healthy roots are so twisted inside the bad ones that I was afraid I might damage them or leave my plant without any roots at all. Is there anything else I can do to fix the problem I created? I won't water it for a week or so because the roots and some soil around it was still pretty wet. Can I possibly cut the little stems that growing on the top and repot them before it's to late? If yes how do I cut it properly? Do I cut them off strait or on the angle?

Answer
You are probably right on your diagnosis of root rot.  Dracaenas are hard to root, so I dont know if that would be a good option, however, you could try one if you want to.  Cut it straight across and dip the cut stem in rooting powder (available at garden centers) and then place it in a vase of water.  Let it sit in indirect bright light until roots have formed and then plant in a pot.  For the root rot, you can buy some Daconil fungicide and treat the soil and roots in the pot with a 2% solution by drenching the entire pot until the water runs out the bottom.  This may save the plant and allow it enough time to grow new roots.  Good Luck.
