I have a cephalotus, labelled "vigorous clumping" which I got from Stephen Morley a few years ago. It is not living up to it's name and has gradually declined over the years, so that it now has only a few non carnivorous leaves about 3-4 mm long. It is just beginning to make tiny new pitchers for this year, but does anybody have advice about coaxing it back into more vigorous growth? It has over wintered in an unheated greenhouse.
