Yellowing Leaves On Our Dracaena Corn Plant

Question

Our 2-year old Dracaena Corn plant’s leaves started turning yellow. We suspected we had over-watered it and root rot had started. We therefore let it dry out a bit and started to re-pot it, but when we took it out of it’s pot, we noticed a white covering everywhere – sort of like mineral deposits. We gently cleaned off the stocks and re-potted it with fresh potting soil. The leaves are now turning yellow at an accelerated pace. On-line research provides conflicting analysis (we over-watered it/it’s dehydrated; we should re-pot it, but the re-potting made it worse; we should fertilize it, but not know because it’s November) We’re so frustrated!

Unfortunately, it is hard to see the status of the soil with the stones on top. It does show signs of overwatering, ONce this happens, it will be best to treat with a fungicide. Here is an article that will help with fungicide use:

When watering you will want the soil to dry to about halfway down the container between watering, since it appears that your container has no drainage to allow extra water out. This article will help you to use a moisture probe:
