You imagine that is so, but the science says otherwise. In fact, most plants can only use sunlight for a few hours a day, and must then endure the heat for the rest of the day. A few crops -- wheat, corn -- offer slightly reduced yields when shaded, but many others -- particularly peppers -- yield better with partial shade. Even where yield is reduced, the extra year-round revenue and radically reduced water loss may even the score.
