Here's word of advice for cephalotus growers. I was so worried about over watering my plants that I severley under watered them. Recently my cephs's leaves and pithers were yellowing and drying up, I thought it was because they were over heating on the windowsill I have them on but then I realized that I was letting the soil dry out for too long between waterings. So now with more frequent watering my cephs are greener (I want them to turn red already, but green is better than yellow) and showing overall improvement. So the moral of the story is cephs really do need plenty of water so don't deprive of it them like I did. Thanx
