Why sudden temperature changes harm plants

Plants respond poorly to abrupt temperature shifts. They can't move to a comfortable spot — they endure whatever you expose them to.

What's happening

Rapid swings disrupt cellular processes, slow water uptake, and damage leaf tissue. Leaves develop brown edges, curl, or drop within days. The plant pauses growth while stabilising.

Why this happens

Moving a plant from a 35°C balcony to a 22°C AC room creates a 13-degree shock. Winter nights in North India are equally jarring for tropical houseplants. Even opening a door between a hot terrace and cooled room creates stressful mixed drafts.

What usually helps

Keep plants where temperature stays stable throughout the day. Avoid AC vent paths and cooler airflow. When relocating from nursery to home, use a shaded intermediate spot for a few days. In Delhi or Jaipur winters, bring balcony plants inside before nightfall when temps dip below 15°C.

What to expect next

Plants adjust within one to two weeks of stable conditions. Dropped leaves won't return, but new growth resumes normally. Pothos, peace lily, and money plant are especially sensitive to cold drafts.
