So far from my experience, 4 parts decomposing granite to 1 part peat works the best. Maybe more peat would be in order? I don't know. Anyway, cover the top with granite chips so it looks good. I'll have to post pictures, this granite media looks 300x better than the peat/perlite...I DON'T reccomend perlite. It floats when top-watering and makes a mess. Stick to the more dense materials.
Naturalized dewy pine sending up 3rd, technically 5th leaf now. My biggest plant has 6 leaves, working on a seventh, and about 2 inches tall.
