A. The sun rises in the east and sets in the west. When rows are aligned north- south, then both sides of the plant receive an almost equal amount of sun and shade. Moreover, the shadow of one row gives shade to the next row. However, if the rows are east- west, then the sun shines more or less all day on the same side of the plants. The rows are unable to shade each other. The side of a double row receiving more sun has a higher incidence of sunscald and skin wrinkle as shown in the photos. Therefore, it is recommended to always plant as close as possible in a north south direction.
