They are all of tropical origin and can not take cold weather. Rich organic matter is the best medium. Peat and compost make excellent media for ferns. Epiphytes that normally grow exposed on large branches are often mounted on slabs of wood or other structure to simulate their natural growing situations. Most ferns benefit from a moist medium and respond to drought by turning a lighter, paler green until they have been given water.
Many ferns benefit from being misted with water when growing in drier environments.
Low to moderate is best. Bright light will cause burning. In a medium rich in organic matter most ferns need relatively little additional fertilizer. Fertilizers high in nitrogen are used when the ferns begin to run out of nutrients. Some of the mites are extremely small and not visible to the unaided eye.
