I recently germinated some Ramonda nathaliae seed, left them under my grow lights, under cover to grow happily to transplant size. Unfortunately the Ramonda are still only tiny with only their seed leaves but moss has taken over the pot. I do this with all my regular (non-alpine) seed and have never had the moss problem because they're usually transplantable well before any moss grows. I have since read that Ramonda grow very slow and should be left in the seed pot for at least a year before transplanting. I'm not discarding the original pot yet although I doubt the little things will survive the moss but I'd like to start another pot. My questions: 1. Should I be using a different seeding mix for alpines ? I am using Premier's Pro-Mix which is peatmoss with perlite and vermiculite. 2. How do I prevent the moss ?
