Boston Ferns $22

Boston ferns are relatively easy to grow as long as you stay on top of two things. Like most ferns, Boston fern needs high humidity to thrive. Misting and setting the plant on a tray of wet pebbles are beneficial. Ignore the need for humidity and you will end up sweeping up small brown leaflets shed by a struggling plant. Keeping your Boston fern's soil (a peaty, soil-based potting mix) consistently moist at all times is key. If the soil dries out, the plant will crisp up and drop many of its leaves. Fertilize potted ferns with a houseplant formula at half strength every month from spring to early fall.

When growing Boston fern as a houseplant, place it in bright, indirect light. When grown in too much shade, a plant's fronds will become dull and sparse. Too much sun, though, and fronds will burn. When growing Boston fern outside, make sure it is sheltered from direct sun to prevent burning.
