Boston Fern (Nephrolepis exaltata) in a pot

Plants/Moderate

Boston Fern

Nephrolepis exaltata

The Boston fern is the definitive hanging fern — arching, ruffled fronds that soften any room.

It is more demanding than most houseplants: it wants consistent moisture, high humidity, and bright indirect light. Reward for meeting those needs is one of the lushest silhouettes indoors.

Common problems

Fronds turning brown and falling

Air too dry. Mist daily, group with other plants, or run a humidifier.

Yellow fronds

Either underwatering or root-bound. Check the soil and repot if roots fill the pot.

Sparse growth

Too little light or nutrients. Move somewhere brighter and feed monthly in spring and summer.

Questions, answered

How much humidity does a Boston fern need?+

At least 50% — 70% is ideal. A bright bathroom is often the perfect spot.

Can Boston ferns live outside?+

Yes, in dappled shade during warm months. Bring inside before temperatures drop below 12°C.

Why is my Boston fern shedding?+

Dry air or inconsistent watering. Both cause fronds to dry from the tips inward.
