With the high temperatures that we experience during the California summer, it is best to water your sod grass lawn in the evening or morning when you get the least amount of evaporation loss. The only exception to this rule is during the establishment of new sod, or when over-seeding with winter grass. During the establishment of new sod grass in California, the high heat will quickly dry out your sod and can cause severe stress that can kill your grass. You must water several times during the day until your lawn is well established. After approximately three weeks, you should be able to reduce your watering to once per day in the evening.
