Shadows from buildings, railings, and overhead slabs shift throughout the day, creating changing light conditions. Understanding these patterns is key to good placement on tight Indian balconies.

What's happening

As the sun moves, shadows sweep across your plant area. A spot with full sun at 9 AM may be shaded by noon due to a neighbouring building. Plants respond to total daily light, not just one moment. Partial shading creates uneven growth.

Why this happens

In dense Indian cities, tall buildings, water tanks, and overhangs create complex shadow patterns. Upper floors get more sun than lower ones. The slab above your balcony provides natural shade helpful in summer but possibly too dark in winter when the sun angle drops.

What usually helps

Observe your balcony at 8 AM, noon, and 4 PM. Note which spots get consistent brightness versus intermittent shade. Place sun-lovers like succulents in long-lit areas. Use shaded corners for ferns and calatheas. Rotate pots weekly.

What to expect next

Once plants are placed by your shadow map, growth becomes predictable. Revisit when seasons change—especially between monsoon and summer.
