Wondering if your balcony receives adequate sunlight for the plants you dream of growing in your urban planter boxes? It's a common concern for city gardeners, but determining your balcony's sun exposure is simpler than you might think. Start by observing your space over several days. Track how many hours of direct sunlight it receives, noting the sun's path and any shadows cast by buildings or railings. Most plants have specific light requirements: full sun plants need 6+ hours of direct light, partial sun/shade plants thrive with 3-6 hours, and shade plants manage with less than 3 hours of direct sunlight.
For a more precise measurement, consider using a sun calculator app or a simple light meter. You can also perform the "shadow test"—sharp, well-defined shadows indicate bright light, while soft, faint shadows suggest lower light conditions. Remember that seasons change sun angles and intensity, so what works in spring might not suffice in fall.
Choose plants based on your findings: opt for sun-loving herbs like rosemary and basil for south-facing balconies, or shade-tolerant greens like lettuce and spinach for north-facing spaces. Don't forget to rotate your planter boxes periodically to ensure even light distribution. With careful observation and plant selection, you can create a thriving urban garden that makes the most of your balcony's unique sunlight conditions.
