You have two whammies here, Kim. Tomatoes won't set fruit (blossoms drop
off) above 95 degrees, and they require deep watering.  I once read where
tomato roots poked about 20 feet down into the soil. It should be obvious
that sprinkling tomatoes won't get water down that deep. Deep water them
once a week or once every 4 or 5 days in your heat. If you use mulch to
conserve soil moisture, you probably can get away with deep watering once a
week. I used to use an irrigator head, but "level" in my tomato patch
became an unknown quantity, so I'm soaker hose watering. I know tomato
roots can only go as deep as about 30 inches here because we have an
inch-thick hardpan at that depth. I only use Epsom Salts when I first plant
tomatoes. Others may use it at other times. Margaret L
