Staghorn Ferns are epiphytes (plants that grow off of other living things), which are popularly mounted on pieces of driftwood or displayed in kokedama balls.
These plants enjoy a humid environment. If the environment has insufficient humidity, it's fronds will require regular misting. They prefer bright indirect light with no direct sunlight.
As these ones are potted in soil, it is best to allow the soil to dry in between waterings. Additionally, watering from below instead of above will also help prevent the base of the plant from rotting over time.
Interestingly, Staghorn Ferns have two leaf types, one is an Antler-like foliage (hence its namesake "stag") while the other is a shield frond at the base of the plant. The latter eventually turns brown (similar colour to parchment paper) and is beneficial for the fern's health and well being. As it protect's the roots and absorbs vital nutrients, it is important to never remove it even though it appear dead.
