I've read (in more than one place) that sheet moss "spells death" for CPs. Why is this stated? I have a pot of Cephalotus which has a magnificent lawn of rapidly growing sheet moss. I have allowed this to trapse into the other highland plants and it looks great growing along with the various forms of living sphagnum. This moss needs pruning espcially around the Cephalotus rosette but I just pull it out 1 cm around the Ceph and Neps and I still get the nice looks of the green moss meadow.
Is the warning so commonly given simply for the more diminutive/delicate plants such as pygmy dosera and such? So far I have seen no ill effects and I love the looks of it.
