Overwintering Boston Ferns: Indoor Care and Spring Division

Boston ferns cannot survive temperatures below 40°F. Bring them indoors for winter, placing them in the brightest light possible. Trim brown fronds as they appear. Consider donating excess ferns to schools or churches for sunny windows. In spring, divide each root ball into eight pieces, plant two divisions per new hanging basket filled with fresh potting soil, and by summer you'll have eight lush baskets.
