While this fern finds it home in the humid tropics, it can be found growing in and around trees. This may seem a little odd but there is a reason for this relationship. First, the tree provides additional humidity and two, it provides shade.
To successfully grow this fern indoor, we must first replicate the two conditions described above.
The first thing we need to consider is the light requirement of this plant. Light can be tricky when it comes to the Bird’s Nest Fern. The best type of sunlight for this plant is bright light without direct sunlight. If the plant receives too much sunlight, the fronds will become light green or will have burn marks. Having said that, there really nothing wrong with letting the plant have a little early morning or pre-sunset light.
