Q: I have a customer with a nobile dendrobium that has asked me about roots growing from higher branches. It is a healthy plant and he wants to repot it so it continues to grow. Should I just leave this high roots alone, they are healthy, and just repot as I would a normal orchid?
A. Usually when roots start on the stems it means the roots below are not happy. My guess is they still have this plant in the deco pot (which doesn’t breathe as well as a terra cotta). Not much you can do other than repot and keep the roots below warm so they can recover. To get more flowers the plant has to grow new canes. Leave the old ones on.
