Some grape-growers attach considerable importance to the direction in which rows run, holding either that the full blaze of the sun at mid-day is desirable for vine, soil and fruit, or that it is detrimental. Those who desire to provide fullest exposure to the sun plant rows east and west when the distance between vines is less than the distance between rows; north and south when vines are farther apart in the row than the rows are from each other. When shade seems more desirable, these directions are reversed. Most often, however, the rows are laid out in accordance with the shape of the vineyard; or, if the land is hilly, the rows follow the contour of the declivities to prevent soil erosion by heavy rains.
