Growing Ferns
Ferns grow well in indirect sunlight exposure. It is a good idea to plant them under the shade of a tree in your yard or indoors near a north or east-facing window, according to the University of Vermont Extension Department of Plant and Soil Science.
Ferns thrive in moist, well-drained rich soil and are most comfortable in humid spaces, such as a bathroom or a warm room in the summertime. In the winter, use a humidifier to increase the room's humidity levels to recreate a comfortable environment for your ferns.
