If your plant does fine in the morning but looks stressed by evening, afternoon sun is likely the problem. In Indian conditions, the difference is dramatic.
What's happening
Morning sun from 7 to 11 AM is gentle—lower intensity and cooler. Afternoon sun from noon to 5 PM is much harsher. Leaf surfaces heat up quickly, soil dries fast, and the combination damages sensitive plants within hours.
Why this happens
By afternoon, air has been heating for hours. Indian summers routinely cross 38-42°C by midday. West-facing balconies catch this peak intensity head-on. Concrete railings and dark flooring radiate extra heat upward, creating an oven effect around pots.
What usually helps
Orient your setup for morning sun and shade after noon. If your only window faces west, use a sheer curtain or set plants back. On terraces, 50% shade cloth—inexpensive at any Indian nursery—works well. Terracotta pots handle heat better than black plastic.
What to expect next
Once afternoon exposure is managed, new leaves emerge healthier. Plants that struggled all summer often bounce back once harsh sun is filtered.
