Boston Fern

Nephrolepis exaltata

houseplant

Boston Fern is a classic houseplant featuring delicate, feathery fronds that arch gracefully from the center, creating a lush, fountain-like appearance. This tropical fern is a champion air-purifier and thrives in humid environments such as bathrooms and kitchens. While it requires consistent moisture and humidity, the effort is rewarded with fast, vigorous growth and attractive, vibrant green foliage.

Care Guide

light_mode

Light

Prefers bright, indirect light; place in an east or north-facing window. Tolerates moderate indirect light but slow growth in low-light conditions. Avoid direct sun which scorches fronds.

water_drop

Water

Keep soil consistently moist (never soggy) by watering when the top half-inch of soil feels dry. Water with distilled or rainwater if possible to prevent mineral accumulation.

compost

Soil

Use a light, airy peat-based potting mix or fern-specific soil that retains moisture while allowing good drainage. A mix of peat, bark, and perlite works well.

science

Fertiliser

Feed every 2–4 weeks during the growing season (spring through summer) with a balanced, diluted liquid fertilizer. Reduce frequency in fall and winter.

thermometer

Temperature

Prefers warm temperatures between 65–75°F (18–24°C). Avoid cold drafts and temperatures below 60°F (15°C), which cause frond drop and decline.

humidity_percentage

Humidity

Requires high humidity (50–80%+). Mist fronds daily, use a pebble tray, or place in a bathroom to maintain moisture. Low humidity causes brown tips and wilting.
