Fertilizer:
When the plants are actively growing, fertilize the plants with 1/4-1/2 recommended strength, applied weekly. A high-nitrogen fertilizer is beneficial from spring to midsummer, but a fertilizer high in phosphates should be used in late summer and autumn.
To avoid mineral deposits building up during periods of heavy fertilization, it is advisable to rinse the containers approximately every month. Rinsing is especially important where the water is highly mineralized. First, water the plant normally to dissolve the accumulated salts, and after about an hour, rinse the substrate with water equal to twice the volume of the container.
Rest period:
Dove orchid needs a rest in winter. Water should be reduced, but they should not be allowed to remain completely dry for long periods. In their natural habitat, during the winter dry season, the light available to the orchid increases because cloud cover is less and the deciduous trees on which the orchid grows lose their leaves. Increased light helps cure the new growths and induce flowering. Fertilizer should be reduced or eliminated until water is increased in spring.
