of our plants are grown in medium or large-grade fir bark.
Fine fir bark can be used for very young plants, but often
holds too much water. Fir bark degrades/decays after
a few years and smaller pieces will decay faster.
moss, both live or dead, is a great though expensive potting
material. It can be mixed with your other potting
materials, or in some cases when humidity is an issue, it
can be used as the potting material. Sphagnum moss
does not decay as fast as bark, and if live will continue
to live in harmony with your orchid.
are lots of other types of barks, moss, and/or other complements
that can be added to your potting mix. A comman example
is the use of perlite, which can hold a large amount of
water. We often add a piece of foam within our pots
to ensure good air flow to the roots.

enough air, the roots will rot, and the plant will likely
roots growing out of the pot? If yes, then the potting
material is too moist. Your plant is putting out roots outside
of the pot to get more air. Check your pot and potting
medium for proper drainage. Some plants grow best
when the potting material is allowed to dry out between
