hello all, Just got my first cephalotus from Meadowvie Biological Research Station, and it's looking pretty good:
hopefully it will do well where it is. I have it in a mix of peat, perlite, and LFS, with live sphagnum covering the top, and it shares a mini greenhouse with tuberous dews, pygmies, and South African plants. DO ignore the fuzziness, the pic was a quick snap through the greenhouse wall.
To tell the truth, I don't have anywhere near an exact idea of humidity, but it is in a nearly sealed greenhouse, so I would guess around 60-80% on average. Since the bottom isn't closed, and it is opened up on a regular basis, there's plenty of circulation. As for the sphagnum, in some of the pots in my other greenhouse it is becoming alomst a weed, outgrowing my carnivores!
If you happen to get a strand of sphagnum sprouting on peat moss on its own, keep it watered with low nutrient/mineral water, and it will do fine. Otherwise, take a strand of sphagnum from another pot, and place it in the new pot. Keep it well watered until it starts growing, and it will keep growing from there. All of the sphagnum in that pot germinated naturally.
