I found this plant to be extremely sensitive to overwatering. I watered it as soon as it arrived and this was a big mistake. Half the leaves on each plant have turned to mush. This stopped after I allowed the soil to dry out. I now only spray the top of the soil occasionally.
I'm very expereinced with keeping houseplants and this was quite a supprise. The plant should come with a warning not to water on arrival and to only water spairingly.
