All plants require some amount of light in order to grow. Nearly all vegetables and fruits (and most flowers) require full sun – 6 to 8 hours of direct sunshine during summer days, between 10am and 6pm. Partial sun (or part shade) refers to plants that prefer to be shaded from direct sunlight during the hottest times of the day, or plants that can grow in sunlight that is broken by fences, overhead trees, and so on. It is possible to grow some vegetable varieties in part shade, including leaf crops, carrots, peas, onions, radish, cauliflower, and cucumber – but all of these will be more productive in full sun.
