While tomatoes need as much sun as they can get, they will not tolerate excessive summer heat. In such areas, farmers often plant a spring crop, and after harvest, wait out the heat of summer, and then plant a new crop in late summer or very early fall, to harvest before the first frost. (Excessive heat will cause the blossoms to fall off without making fruit)
