100-Year-Old Heirloom Fern Decline: Watering, Humidity, and Repotting

A century-old fern (never outdoors) shows brown fronds and dying "breathers" after summer watering every 7–9 days. Expert Darlene advises:

Ferns need constant moisture—never totally dry out.
Water more frequently; use bamboo skewer to test (water when dry 1/4 down).
Mist foliage twice daily for humidity.
Open drapes for more dappled light (hand should cast shadow).
May need division/repotting in spring—consult local florist or extension.
Dry indoor air (heating) worsens condition; mist more.

Follow-up: fern never moved in 100 years, no new fronds. Could need repotting/division in spring. Local expert examination recommended. More misting may help.
