I inherited this small dracena tree from a friend who moved out of province. about 2 weeks ago i repotted the plant because it was extremely rootbound (same pot for about 3 years). the pot had drainage holes of sorts, I put it in one of those bottom watering pots which I'm thinking was a mistake. Since repotting the plant has dropped at least 15 of its lower leaves. I know this is natural as that is how the tree develops a trunk, however I'm afraid it's losing too many too fast. The soil is still quite moist despite only watering it once since the repot about a week ago. I'm terrified the yellowing, dropping leaves are a sign of root rot. it's in a West facing basement window, and I leave a plant light on near by to supplement the lack of light. I also bought a warm humidifier to help keep the temperature up in my basement suite. should I leave the plant alone and stop worrying or should I repot into a normal pot with real drainage holes? thanks so much!!! BTW. I just removed all of the yellow leaves, so the yellow you see in the image is just from the plant light.
