Tomatoes are sun-loving plants, but they are susceptible to sun exposure in very hot and sunny environments, especially if their foliage is sparse. The solution given is to provide a black net to shade the tomatoes. Shade for tomatoes can actually increase their yield. In fact, a study of tomatoes in a commercial growing environment found that sun-shaded tomatoes had a 40% increase in leaf area and a nearly 50% increase in yield. Sun protection of tomatoes also produces beautiful, succulent fruits.
