Fertilizer:
Weekly or every 2 weeks use of a 1/4-1/2 dose of orchid fertilizer is recommended. Balanced fertilizer should be used for a round year.
Rest period:
Dendrobium purpureum cultivated in the conditions of a dark, short day at moderate latitudes should reduce the amount of water in winter. However, they can never dry up completely. When reducing the amount of water, fertilization should be reduced or eliminated.
