Answer: Watering 3 times a day is excessive and you can damage the roots of your plants when you keep the soil constantly moist. Taper off until you are watering your lawn twice a week and your plants once a week. You need to apply water for long periods of time (about 15 minutes) and slowly so the water has a chance to percolate down into the soil. Infrequent, deep watering will moisten the soil deeply, which is where you want the roots to grow. Daily watering will make the roots remain close to the surface where they will rely on frequent watering and wilt when they don't get it. So, water deeply but no more than twice a week and your plants and lawn should be fine.
