I'm curious - I have no plants in live sphagnum yet, but I would like to - so, how do you create the pot? Do you fill it halfway with pure peat (or LFS?) and toss live sphagnum on it, then just put the plants in so the roots are in the live sphagnum? Or is live sphagnum only meant as a top dressing?
Do you need to add perlite/sand?
For what CP's is live sphagnum an acceptable or even preferred medium?
