Water is critical for seed germination. Grass seedlings can die quickly from lack of water and even a mulched lawn needs enough water to keep the soil surface moist.
A fine spray delivers the best coverage. The water should fall on the ground evenly without forming puddles or causing run-off.
Water each day until germination, then gradually cut back until the lawn is established.
When your grass begins to wilt, waterthoroughly with 1 inch of water. This deepwatering encourages grass roots to grow straightdown, making your lawn less susceptible todisease and heat stress.
The best time of day to water is in the early morning when evaporation rates are lowand grass can dry completely. If you water in the evenings, the grass doesn't have enough time to dry, and excess moisture makes the lawn susceptible to disease.
Helpful Hint: To measure how much water your lawn is getting, set empty coffee cans on the grass where they can catch water from your sprinkler. Check them periodically, and when 1 inch of water has collected, turn off the sprinkler. Make a note of how long it took for that 1 inch to accumulate and remember it for next time.
