Hi! I got this plant more than a year ago and it has been thriving since. Last month, I was getting multiple new leaves every week! One or two weeks ago though, some leaves started yellowing and dying and I have no clue why... It used to be only one or two old leaves but now more half of them are fading yellow, even the newest ones! One is even becoming black and dying. I has been in the same spot for a year and I haven't really changed anything. I need help fast as it is deteriorating quickly!
Thanks!!!

As plants grow, their roots do as well. That means they require more water, so I suspect your unvarying watering routine needs to be adjusted so the soil does not get so dry between thorough waterings.

I had the same problem. Looked wonderful when I bought it then it slowly declined. I found out it had pests and sprayed it with Neem, which worked to eliminate them. Now, I make sure to keep it moist but not soaking. If it's not in the right conditions, it will get pests. Is it getting enough water and filtered light? These plants like filtered direct light (through a sheer curtain) and moist, not wet conditions. Here's mine now. All the best.

Old thread, but curious how it turned out.
