The best way to beat the heat for your lawn is by watering. One inch of water per week keeps turf grass healthy. Once you start to water don’t stop. Less frequent, deeper waterings are better than frequent shallow ones. Watering for longer periods of time less often will promote deeper roots, greater drought tolerance and less maintenance. Water your lawn in the morning when it is cool to allow more water to soak into the ground rather than evaporate. Avoid watering in the evening to prevent fungus and disease. Make sure you have functional and easy to use watering equipment to make the process fool-proof.
Also; Keep the Grass Longer in Summer.
Grass has a crown from which new growth emerges. If you keep the lawn longer in the summer, the blades shade the crown and protect it from burning.
