Why live versus dried sphag? Is it microbes and added humidity that make the difference?
I definitely see better response to live sphag. I can speculate why...
Sphagnum always has antimicrobial activity, but some compounds will be lacking in dead moss as it ages, and dead moss doesn't react to the environment. Live moss may actually respond to the presence of pathogens.
Most plants will grow better surrounded by healthy growing neighbors in a living environment than in sterile isolation. Sphagnum provides that without crowding or shading.
