Boston Fern

A healthy Boston fern is a cascade of arching green fronds, each one finely divided and gently ruffled. It is a classic for hanging baskets and porches, and indoors it brings a softness few other plants can match.

It is also honest about its needs. A Boston fern in the wrong spot will shed a steady drizzle of tiny brown leaflets. In the right spot, with moisture in the soil and in the air, it is easy and grows fast.

At a glance

• Light: bright indirect light. Hot direct sun scorches the fronds.
• Water: keep the soil evenly moist; do not let it dry out.
• Humidity: high. Bathrooms with a window are ideal.
• Pets: non-toxic to cats and dogs.
• Price: $24 for the 6-inch size.

Watering and humidity

Ferns have fine roots that dry out quickly, so check the pot every few days and water as soon as the surface feels dry. In warm weather that can mean twice a week. The other half of fern care is humid air. Central heating dries a room out fast, and a fern in dry air will brown at the tips and drop leaflets. A steamy bathroom, a kitchen near the sink, or a group of other plants all help.

Where to put it

Because the fronds arch and spill downward, a Boston fern looks best raised up. A hanging planter near a bright window is the traditional choice, and the drip tray catches the water these thirsty plants need. A tall plant stand works just as well.

Through the year

Ferns grow most from spring to autumn and slow down in winter. Brown fronds are normal now and then; cut them off at the base to make room for new ones. If the plant fills its pot and dries out within a day of watering, it is time to move it up a size.

Pets

Boston fern is listed as non-toxic to cats and dogs, and it is one of three plants in our collection for homes with pets. Hang it out of reach anyway, as cats love to bat at the fronds, and call your vet if a pet seems unwell after eating any plant.
