Hi, I got these Dracaena last September, and the leaves of on stalk started turning yellow a month later. the plant is still in the original white plastic pot. i never repotted because i think the pot is big enough. I read on line and realized that i might be over watering the plant. so instead of watering it once a week, i've been doing it monthly starting in December. But these leaves continue to turn yellow then brown. and now i noticed leaves from another stalk is starting to turn yellow too. I thought maybe the poor performing stalks wasn't getting enough light (they were closer to the wall). i just rotated the plant so the yellow stalks are now closer to the light. I hope that will help. The plant is sitting next to a sliding door, and there is a heat vent next to it if you can see from the picture. i am not sure if that's the problem because only one stalk is doing poorly and that was the one most away from the heat and the sliding door. can you please tell me what else i should do to save my plant? thanks!
Does look like it is being affected by sitting in water. Have you been emptying the water out of the bottom of the outer pot?
