Deep and infrequent watering maintains a healthy root system and reduces weed infestation (as opposed to light and frequent irrigation, which promotes shallow roots and germination of weed seeds).
Water is best applied early in the day (5 am to 10 am) when evaporation loss is lowest. Afternoon watering is acceptable but wind may affect uniformity. Night watering minimizes evaporation, but may increase fungal diseases.
Consider that numerous automatic sprinklers all running during periods of high household use (early morning) may place extreme demands on a community's water system.
Water the lawn, not driveways, sidewalks, or roads, by adjusting sprinkler heads.
Mow your grass at the right height during the summer. Longer grass blades increase the depth of the root system, shade the soil, and help drought tolerance.
If your current grass is not drought tolerant, consider replacing it with one that is.
Remember that newly sodded or seeded lawns require more frequent watering (for the first 3 to 4 weeks) than do well established (older than 12 months) lawns.
Keep your mower blade sharp.
Annual core aeration can loosen compacted soil and allow water to infiltrate deeper into the ground.sible.
