Be sure to check by municipal by-laws for outdoor water use so if you need to water be sure to water deeply and less frequently to create a healthier and stronger lawn.
Early morning watering
The best time to water is early morning before day time and rise of the temperature because the low-temperature level supports absorption rather than evaporation. If you water your lawn early in the morning it will keep the stress level low for the lawn and keep the turf cooler.
If it is not possible for you to water early in the morning then keep the watering time in the late afternoon. Try to avoid watering in the late evening or at night as evenings and nights are long periods of dampness which increase the chances of disease and fungus.
Ensure soaking quantity in the soil
Soaking the water to 6 inches down in the soil is recommended by the gardening experts. This the ideal water soaking level to get a healthy grown grass and root system. But also remember that each lawn soil needs to soak different quantities of water in it so, one way to prevent over-watering is to buy a rain gauge.
A rain gauge is inexpensive and tells you exactly how much water your lawn has received, and it let you know that you don't need to water it at all.
Another way is using a long-blade screwdriver for the water level testing in the soil. Just shove it into the soil and it should go down about 6 inches in the soil easily. But, if you feel it hard to reach the 6 inches depth then it means that the soil is not soaked properly.
