Help! I think I'm losing my Black Rabbit's Foot Fern! I received two plants, one was planted in the soil close to the waterfall. That one rotted away pretty quickly. The other I planted in a hole in my artificial tree. (The hole goes all the way down to the false bottom. Is filled partway up with Leca, then soil - So plenty of drainage). This fern also lost several fronds. I figured the one that died the fastest was way wet so I stopped misting this one directly. But it's slowly dying back I think.
