i've recently bought a peperomia caperata from kmart, they were standing so straight and so beautiful. i got some tips off the net bout caring for them and some suggested misting and so i did a bit of misting everyday. n not sur if this is the reason but some leaf started wilting and others' stems went limpy...dont no whether its the light factor either, already try not to give it just a little bit of light (seeing that they grow well considering they were in kmart with no natural light at all in air conditioning)..... so if anyone knows how to care for them properly tell me please.... they are dying....dying.....
Well, from my experience they do like bright indirect light, but your problem sounds more like a watering problem. They do like to be kept a bit moist, but should dry out a bit between waterings. They are very sensitive to overwatering and will quickly rot if they get too much water. Cut away all the leaves that are dying and you may be able to save your plant, butif the stems themselves are limpy and rotten then there isn't much you can do to save your plant.
