Question for the experts: I got these two plants about 2 weeks ago, the app says they’re Button Ferns. The sad one went from healthy to looking like this within 2 days. It is in a morning sun location, shade in the afternoon, by an open window. Its buddy (pictured) that I got at the same time was in the same location and still looks good. The pots have a removable drainage hole, so I put them in the sink when I watered them. I believe I’ve only watered them once in the previous two weeks. Give it to me straight, can this dude come back? What do I need to do to make sure I don’t lose the other one? Many thanks for your guidance!
