I am a neophyte in the orchid world, but I do have 1 Phalanopsis which
has bloomed each year for the past 3 and is preparing to do so again.
I wonder about repotting it, which I have never done before. I assume
I should wait until it is done blooming. Some instruction indicate to
remove all the old potting medium from the roots and stuff the plant
into new medium. Seems rather harsh compared to repotting other
houseplants. What is the best procedure for repotting? What is the
best commercial potting medium to buy?
