Dracaena Marginata Dying
I bought a potted Dracaena - it had 3 stalks. I probably over watered coz I found mold growing on the pot. I re-potted and cut back on watering. In the new pot initially the plant did well. A couple of days ago I noticed that one of the stalks got a little puffy. I felt the roots of the stalk and on one side the root seemed a lil puffy too. The leaves of that stalk are now drooping, turned yellow and falling off. The other stalks are doing fine. I give it 3/4 cup of water every week and fertilize it once a month with fertilizer sticks (that one has stick into the pot). I also found out that my son had given the drooping stalk a big shake up thinking it was already dead. I dont think the poor stalk will survive that :( Should I repot the healthy stalks? Does anyone have any advice for me?
