About a month ago I purchased a starter medinilla magnifica after running into a mature plant in a store and falling in love with the flowers, but not the price tag (no way I was paying $60 for a plant!).
To keep my explanation short, I initially overwatered the plant, so it lost about half its leaves, and the ones it did keep began to blacken. I trimmed back the blackening parts and got the hang of watering, so its condition is not deteriorating quite so quickly, but its leaves are still slowly blackening and every so often it drops a leaf.
I'm not worried about heat or humidity, I have a maranta that is flourishing and the two plants like a similar temperature/moisture level.
What can I do to keep my plant from completely dying?
The plant dropped its 2 blackened leaves since last night.
Unfortunately the plant died a few days ago. Maybe someday I'll try again someday.
As an update since this post has gotten a lot of views, I got a new starter medinilla magnifica about six months ago and it's doing well. I keep it in front of a west-facing window in a bathroom so it gets lots of humidity from showers, and I water it only when its leaves begin to droop. I have not yet repotted it from its original container. It has been growing slowly but steadily, and I'm hoping in a few years' time I'll have a flowering plant.
