Yeah, they aren't as hardy as some plants(Pothos, Schefflera arboricola), I usually ahve three or four out of rotation that I can bring outside and when I clean their cages I usually rotate them out. If you are having this issue a lot try a Schefflera arboricola instead of a Schefflera actinophylla. I find these last longer. Also I guess how long are they lasting until the die?
