Use alone as
an orchid medium or as an additive to other potting mediums. It can be
used in both plastic and terra cotta pots with great success. Mini-catts
(and possibly other orchids) grow beautifully when a collar
of sphagnum is put around the plant and the roots are allowed to remain
free in the pot below.
Sphagnum moss can also be used to retain moisture on plaques.
