Growing Boston Fern as a Houseplant
Indoors as a houseplant, Boston fern appreciates medium to bright light. Keep it out of direct sun, especially during the afternoon hours. While the plant can tolerate low-ish light conditions, it does best where it casts a soft shadow much of the day.
Water Boston fern as the potting mix starts to dry to the touch. How much and often that is depends on a variety of factors, including temperature and relative humidity levels. It's best to probe the potting mix with your finger or a moisture meter to get a sense of whether your plant needs water.
