Why tropical plants struggle in winter

Winter conditions can be challenging for tropical foliage plants.

What's happening

Reduced daylight and cooler temperatures slow growth and water uptake. In north India — Delhi, Jaipur, Lucknow — December nights can drop below 10°C on open balconies, well below the 20–30°C these plants prefer. Even in the south, shorter days mean less photosynthesis.

Why this happens

Tropical plants evolved in warm, stable climates with little temperature or daylight variation. Indian winters, especially up north, create conditions they are not built for. Cold drafts, reduced sun, and dry air from heaters compound the stress.

What usually helps

Reduce watering — the plant uses less water when growth slows, and overwatering in winter kills. Move plants from cold drafts to morning-sun windows. Keep them a metre from heaters and place a water tray nearby to counter dryness. Skip fertiliser until February–March.

What to expect next

Growth picks up by late February as warmth and daylight return. Some winter leaf drop is normal — focus on keeping roots healthy and the plant bounces back in spring.
