Remove the phalaenopsis from the pot using your fingers or a dull chisel. Remove as much old medium from the roots as possible.
If there are any roots that are dry or mushy, use sterilized shears to cut them off.
Find a flower pot which will accommodate the roots of the phalaenopsis comfortably.
Plastic pots if used, are lightweight and phalaenopsis tend to have tall flowers spikes, we will use a few small rocks or stones as drainage material to keep the phalaenopsis from being top-heavy.
Center the orchid in the pot with the base of the leaves about one-half inch below the rim of the pot. Next you can add moistened fir bank, until it is up to the base of the leaves. Allow the leaves to sit above the medium. Do not bury the leaves.
Pot clips can be used to anchor the plant by pressing the medium against the root.
Sterilized fir bark is probably the most commonly used orchid potting material. The relatively uniform pieces readily fall into place among the orchid roots. Fir bark may be resistant to water at first, so soak before use.
