Every property is different however a good starting point is 30 minutes per rotary zone and 15 minutes for misters every other day starting at 1AM and stopping by 6AM during the early spring and fall and 30 minutes per rotary zone and 15 minutes for misters EVERYDAY during the hottest summer months of July and August.  However please remember many conditions such as shade, and soil conditions play a large factor on the amount of water that is ideal for a property. Please speak to your irrigation or maintenace technician if you are unsure about watering times.
