Hi everyone! I was gifted this beautiful Hydnophytum and wanted to mount it on some tree bark since that reminded me of what the plant looked like when I was traveling in Borneo last year. I put a fistful of sphagnum moss between the plant and the bark and then supported it with a wire. It seems the leaves are going yellow and dropping now. I'm not sure how moist I am supposed to keep it. In terms of light, it gets an hour or so of direct morning sun and then 400 foot candles of indirect light all day after that. Would love any tips people might have. Not a lot of info out there I can find!
