About

A Living Curtain of Green

Boston Fern is one of the most beloved houseplants in the world, and for good reason. Its long, arching fronds - each lined with dozens of paired leaflets - create a full, billowing silhouette that softens shelves, pedestals, and hanging baskets with effortless elegance.

Native to humid tropical forests from Florida to South America and beyond, Nephrolepis exaltata thrives where moisture and warmth are constant. Indoors, it performs best in rooms with good humidity, making it a natural fit for bathrooms, kitchens, or any space with a humidifier nearby.

How to grow

Planting & care

Plant Boston Fern in a rich, well-draining potting mix with plenty of organic matter. Choose a container with drainage holes to prevent soggy roots. Position it in bright, indirect light - a north- or east-facing window is ideal. Avoid direct sun, which scorches fronds quickly.

Water consistently to keep the soil evenly moist but never waterlogged. Mist fronds regularly or set the pot on a pebble tray with water to boost humidity - this is non-negotiable for healthy growth. Feed monthly during spring and summer with a balanced liquid fertilizer diluted to half strength. Trim brown or yellowing fronds at the base to encourage fresh growth.

Good to know

Frond Shed Got You Worried?

Boston Ferns are notorious for dropping leaflets (pinnae) when stressed by low humidity, dry air from heating vents, or inconsistent watering. Before you give up, move the plant away from drafts, increase humidity, and settle into a steady watering routine - most ferns bounce back surprisingly well once conditions improve.
