Medium and high. When encouraging orchids to set bloom, bright light is necessary. When in bloom, they can be moved to a less bright location to extend bloom time.
Medium. Moth Orchids grow in trees and their roots don’t like constant moisture. But, they won’t thrive if kept too dry. If your plant has air roots they will be silvery-greenish and full when plant is hydrated. When dry, the air roots are all silver-grey.
Orchids are happiest in humid conditions, with moderate temperatures. Use Orchid Bark when re-potting. Moss can be used if conditions are too dry, to retain moisture. Fertilize with an orchid growth formula when plants are out of bloom or during spring and summer. Use an orchid bloom formula fall and winter. “Weakly, weekly” is the usual rule for fertilizing.
Only re-pot when plants are over grown and out of bloom; orchids perform best when crowded in their containers. Bloom time is usually late fall, winter, early spring with temperatures a cooler.
