I'm new to this group of plants and find the dormancy cycle nice. But am unsure of when to start watering. I am seeing new growth, but the medium they are in now is sphag and unable to see any roots other than last years. Second question, when do I repot them? I'm thinking of keeping the medium in now - sphagnum, and in very good condition still - and just putting into a bit larger pot with some chc, perlite, type mix. Any suggestions on growing this alliance would be absolutely appreciated!
