Reviving a Tropical Hibiscus After Winter Leaf Drop

Reviving a Tropical Hibiscus After Winter Leaf Drop

Bringing a tropical hibiscus indoors for winter in Zone 7 often triggers dramatic leaf yellowing and drop. The plant isn't dead—it's in shock from the sudden change in light, humidity, and temperature.

Why It Happens

Tropical hibiscus thrives in warm, humid, bright conditions. Moving it indoors to dry, heated air with lower light causes stress. The plant defoliates as a survival response. If the main trunk shows green under the bark, it's alive.

Care During Dormancy

• Don't overwater. Keep soil barely moist, not wet.
• Maximize light. Place near a large south-facing window or under a grow light.
• Avoid hot, dry air. Keep away from heating vents; use a humidity tray.
• Wait. New growth may not appear until spring when the plant moves back outside.

Pruning

Do not prune until you see new growth. Once buds swell, cut back to live wood. This encourages bushier growth and more blooms.

Patience is key. Many hibiscus recover fully and bloom vigorously once returned to their preferred outdoor conditions.
