Overwintering Braided Ficus in Cold Climates

A Quebec gardener (Zone 4, –20 °F) has two braided Ficus benjamina trees that spent summer outdoors. Last winter, bringing them inside caused massive leaf drop. They seek a strategy to prevent recurrence.

Ficus benjamina is tropical and cannot survive freezing temperatures. They must come indoors. The leaf drop is a normal response to reduced light intensity indoors—chloroplasts in "sun leaves" are arranged for high light; when moved to lower light, the plant sheds them and grows new "shade leaves" adapted to interior conditions. This is not a care failure.

To minimize shock:

• Move plants indoors before night temperatures drop below 50 °F (10 °C).
• Place in the brightest possible location—south or west window, or under full-spectrum grow lights (12–14 hours daily).
• Maintain temperatures above 60 °F (16 °C); avoid cold drafts and heating vents.
• Water only when the top inch of soil is dry. Reduce frequency in winter.
• Increase humidity: use a pebble tray, humidifier, or group plants together.
• Do not fertilize until new growth resumes in spring.

Expect some leaf drop during transition. Within 4–6 weeks, new leaves adapted to indoor light will emerge. The plant will stabilize and resume growth.
