Reading your balcony's sunlight before you buy a single plant

Ask most people how much sun their balcony gets and they'll guess: "pretty sunny," maybe, or "kind of shady." It's usually wrong. Sunlight moves through a day in ways that are hard to hold in memory, especially once a building or a water tank across the street starts throwing shade at odd hours. Before buying a single plant, spend one day actually watching it.

The three light categories that matter

• Full sun: 6+ hours of direct sun. Typical for south- or west-facing balconies in most Indian cities.
• Partial sun: 3–6 hours of direct sun, often morning-only or filtered through a neighbouring structure.
• Low light / shade: under 3 hours of direct sun. Common on north-facing balconies or ones shadowed by taller buildings.

A one-day sunlight audit

Check your balcony at four points during a clear day and note whether it's in direct sun, bright shade, or full shade:

• 9 AM
• 12 PM
• 3 PM
• 5 PM

Add up the direct-sun hours. Do it once on a clear day, and if you have the patience, repeat the check a few weeks later. The sun's angle drifts across the seasons, so a balcony that's full sun in May can slide to partial sun by December without anything about the balcony itself changing.

Orientation on its own is a starting guess at best. A technically south-facing balcony can still sit mostly in shade if a taller tower is close by, which is common enough in dense Indian neighbourhoods that it's worth checking rather than assuming. Trust what the audit tells you over what the compass suggests.

Matching plants to what you measured

Once you know your category, plant selection stops being a gamble. Full-sun spots suit marigold, hibiscus, and most vegetables. Partial-sun spots work well for curry leaf, aloe vera, and many herbs. Low-light balconies do best with money plant (pothos), ZZ plant, and peace lily, plants built to hold on in shade rather than just limp along in it.

Buy for the light you actually measured, not the light you were hoping for.
