No matter whether you are cultivating a field, a garden or a balcony, your gardening activities are subject to changing seasons. When your balcony is located on the second floor in a narrow street lined with five-story houses, sunlight hours define the course of the year. While there are some days in winter during which the sun never rises high enough to climb over the neighboring house’s roof, you learn to appreciate rays of sunlight crawling over your breakfast table in summer. Now in August, the sunlight hours already get perceptibly shorter. It was twenty past nine this morning when the sun sat on the roof top, just to hide behind the chimney again few minutes after.
