I bought a Ctenanthe a while back and it has been good ever since. I keep it in a medium bright spot, no direct sunlight, and always a pretty stable temperature.

Recently I have seen some brown leaves, and leaves looking pale as well. I cut away the completely rotten leaves, but after a week, other leaves are dying as well. On the other hand, it is sprouting a lot of new leaves as well. That's why I'm a bit confused about what's happening.

I attached some pictures to help diagnose the problem. I am wondering what I should do to fix the plant.

Christophe, is there a pot within the pot? If so, I'd pull it out and see how the roots look. Granted leaves do get old and die, but, I still would check the roots. Leaves can die whether too much or not enough water. The roots need oxygen as well, Yea, kinda catch 22.You may have to repot it. Please let us know what you find,appreciate it. Love the plant.

  • The pot is indeed supsended in the bigger pot. It's the pot it came in from the store. The roots look a bit brownish. I guess this is root rot? Repotting it and then making sure it gets enough of oxygen would be the fix? – Christophe De Troyer Jan 4 '18 at 7:39
  • Christophe, if the roots are mushy, that's root rot.If there's more root than dirt,re-pot. Rule of thumb go about 2-3 in. bigger than the original pot. If the roots are going around & around the pot, go a little bigger.Letting a plant dry out Slightly, will let more oxygen in. Remember, no need to fertilize, new soil has plenty of nutrients. Wait until spring. Love the big pot, but I think your better off putting that somewhere as a visual piece. Let me know how you make out. – Donna White Jan 5 '18 at 12:44
  • Okay so I took it out of the pot. It had some white moldy-looking stuff on it here and there so I guess that is mold. The bottom 1/3rd part of the roots was brown and mushy, so I trimmed that off. I was left with a coconut sized ball of white thick roots. I re-potted in general purpose soil in the same pot. I think it still has some room to grow. I have not watered yet, as per your recommendation. I will come back and tell you how it's doing soon :D Thanks for the information! – Christophe De Troyer Jan 9 '18 at 11:10
  • I'm glad you checked! I hope it survives, water isn't always our or their friend. Actually the markings on it reminds me of a prayer plant just bigger. Prayer plants' leaves roll up at night and unfold during the day, pretty cool. Thanks Christophe. – Donna White Jan 9 '18 at 19:41
  • This plant does the same kind of thing. The leaves don't roll up, they just flap inward. It's nice to see in the evening while watching tv :) I really enjoy this plant! Thanks for the advice! – Christophe De Troyer Jan 10 '18 at 14:24
