Boston ferns (Nephrolepis exaltata) are popular houseplants and proper care is essential to keeping this plant healthy; learning how to take care of a Boston fern isn’t difficult, but it is specific.
Boston ferns need a cool place with high humidity and indirect light. When you care for Boston fern plants indoors, it’s a good idea to provide additional humidity for them, especially in the winter when most homes' heaters are running and are rather dry. Boston fern leaves will turn yellow if the humidity is not high enough. If your Boston fern’s fronds are turning yellow, make sure to increase the humidity around the plant
Make sure that the fern’s soil remains damp, as dry soil is one of the number one reasons that Boston ferns die. Check the soil daily and make sure to give it some water if the soil feels at all dry. Because Boston ferns tend to be planted in potting mixtures that are high in peat moss, it is a good idea to soak the pot of the Boston fern once a month or so to make sure the peat moss is fully hydrated. Be sure to let it drain thoroughly after this.
