Light is the first thing to measure on a balcony. A space that looks bright can still receive little direct sun if nearby buildings, railings, trees, or an overhang block the sky. The goal is to observe the light you actually have, then choose plants that suit it.
Direct sun versus bright light
Direct sun means sunlight reaches the leaves without an obstacle. Bright indirect light can still be excellent for many houseplants, but it is not the same as the strong, direct light that fruiting vegetables and many sun-loving herbs need. If the sun creates a defined shadow of your hand, you are likely seeing direct sun.
Measure it for several days
- On a clear day, check your balcony in the morning, around midday, and late afternoon.
- Write down when direct sun begins and ends.
- Repeat on another day if clouds, nearby construction, or seasonal tree cover may affect the result.
- Notice the hottest time of day and the windiest corner.
A phone note is enough. You do not need a complicated meter to make a useful first decision.
Use practical light categories
Full sun is often described as six or more hours of direct sun. Partial sun is roughly four to six hours. Shade receives less direct sun, although it may still be bright. These labels are guides: intense afternoon sun can be harsher than the same number of morning hours, particularly near reflective walls, glass, or concrete.
Direction changes the experience
East-facing spaces commonly get gentler morning sun. West-facing balconies can become hot in late afternoon. South-facing spaces in the Northern Hemisphere may receive the most sun, while north-facing spaces are often lower-light. Buildings and overhangs can change all of these patterns, so orientation is a clue—not a measurement.
Choose plants after observing
For a sunny balcony, start with plants whose labels call for full sun and provide enough water for containers. For partial sun, leafy greens, some herbs, and shade-tolerant flowers may be more realistic than large fruiting crops. In low light, focus on plants that are labeled for shade or bright indirect indoor light. Matching plants to existing conditions is more dependable than trying to force a sun-loving plant into shade.
Safety and comfort matter too
Hot balconies dry pots quickly and can make dark containers extremely warm. Use stable pots, secure any trellis according to building rules, and never let a planter or tool hang where it could fall. Check water needs more often during heat, wind, and dry spells.
