The key to a healthy bird's nest fern is providing enough warmth and moisture. Given these two conditions, the ferns can withstand higher light levels. One of the best places to put a bird's nest fern is on a shower ledge or the wide edges of a luxury bathtub in a bathroom near a window, where it will get optimal humidity and warmth, along with sufficient light.
These plants need filtered light to light shade. Don't expose to direct sun other than the very early morning sun.
