Boston Fern
Nephrolepis exaltata
Lush, billowing fronds for high-humidity sanctuaries
About Boston Fern
The Boston Fern is the classic hanging plant, with its long, arching fronds of feathery, bright-green leaflets creating a lush, wild aesthetic. It's one of the best natural air humidifiers — as it transpires moisture through its leaves, it naturally raises room humidity. Bathrooms and kitchens are its natural habitat. While it requires more attention than many houseplants, its lush, cascading form is unmatched.
Complete Care Guide
Watering
Keep soil consistently moist but never waterlogged. Water when the top inch of soil begins to dry. Boston Ferns are more sensitive to drying out than most plants — missing a watering can cause rapid browning.
Light
Bright, indirect light is ideal. Near a north or east-facing window works beautifully. Avoid direct sun, which scorches the delicate fronds.
Soil
Peat-based potting mix that retains some moisture while draining well. Adding peat moss or coco coir improves water retention.
Fertilizing
Feed every 2–3 weeks during spring and summer with a balanced liquid fertilizer at half strength. Boston Ferns are moderate feeders.
Repotting
Repot annually in spring into fresh, moisture-retaining potting mix. The dense root system depletes nutrients quickly.
Pruning
Remove brown or yellowed fronds at the base. Cut back leggy growth in early spring to stimulate fresh, lush growth.
Common Problems & Solutions
Brown, crispy fronds
Low humidity is the primary cause. Mist daily, use a pebble tray, or run a humidifier. Also check soil moisture — drying out causes rapid browning.
Shedding leaflets constantly
Normal behavior, especially in winter or after relocation. Ensure humidity is adequate and avoid cold drafts and dry heat from vents.
