When is the best time to water a lawn?
Early morning (5:00 to 9:00 am) is the best time to water a lawn. A morning application allows the water to soak deeply into the soil with little water lost to evaporation. When watering is completed, the turfgrass foliage dries quickly. Watering at mid-day is less efficient because of rapid evaporation and strong winds may cause uneven water distribution. Strong, mid-day winds may also carry water onto driveways, sidewalks, or streets, wasting considerable amounts of water. Watering lawns in late afternoon or evening may increase disease problems.
