Overwintering Boston Fern in Kentucky: Indoors with Humidity

A rescued Boston fern (Nephrolepis exaltata) thrived on a deck all summer. Owner in Kentucky (winters below zero, 20s°F) asked whether to bring it in and how to manage low light/humidity.

Must Come Indoors

Not hardy in Kentucky. Needs:

• Bright window with decent light.
• Humidity: Brown tips indicate dry air—use pebble tray, humidifier, or bathroom placement.

Alternative

If home conditions can't meet needs, gift it to someone with a big sunny window who'll appreciate the rescue story. Victorians loved these; they're stunning when happy.

Don't struggle—find it a better spot or a better home.
