Cephalotus is sussceptible to rot at all times. The best
success I personally had with it was using live spaghnum,
which seemed to give plenty of soil aeration. Repotting
also takes it's toll on the plant, which seems to REALLY
dislike root disturbance. People I've known who repotted
or divided their plants had all the above ground pitchers
die and the plants had to come back from the rhizome.
My Ceph. is currently jus sitting around dormant. This winter
I lost one of the two growth crowns to rot. It was the wettest
winter CA has had in years, and I lost a number of plants to
fungus.
