Most people assume ferns thrive in the shadows, but these houseplants need some light, so don’t hide them in dark corners. Medium, indirect dappled light will bring out the best in them (picture them under a thick canopy of trees on a sunny day). Avoid direct sunlight.
Ferns need constant moisture, but don’t let them sit in standing water. Only certain types of wetland ferns can live in that environment. More importantly, do not neglect to water your fern. When that happens, you will find a dying fern surrounded by a ring of brown, crunchy leaves.
Ferns adapt easily to most household temperatures. They prefer to live in cooler temps but can withstand temperatures into the 90’s. They’ll just need more water and shade during a heatwave.
Humidity is a MUST in order to keep your fern strong and vigorous! If you think about the tropical rainforests where they naturally grow, it’s easy to see why. A humidifier will be the best solution to raise the humidity in your home during the cold months when the forced-air heat is cranking and dries out the air. Misting your plants is a temporary fix; if you’re able to mist multiple times daily that will help. If you can’t mist often, then place the ferns on a tray filled with pebbles and water so the evaporating water can reach the foliage.
