bathroom placement on Boston Fern
Quick answer
If your Boston Fern has bathroom placement, the most likely cause is: Bathroom placement works for Boston ferns because ambient humidity from showers (60-90% RH) maintains the 60-80% range hygrophilous ferns require without manual intervention. Fern frond desiccation from low humidity occurs when indoor air drops below 50% RH — bathrooms naturally stay above this threshold due to steam from daily shower cycles.
Start here:
- 1. Position fern on a shelf or windowsill 3-5 feet from the shower, away from direct water spray
- 2. Ensure bathroom has a window with filtered indirect light — ferns need 500-2000 foot-candles

Avoid placing near heating/cooling vents that would dry air and drop humidity below 50% RH
- 4
