Mowing
When mowing, the best time to mow is in the evening after the sun has set. This will help keep you cool and the grass roots moist. When you mow, only mow about ⅓ of the height. Removing too much grass will allow the grass to get hotter in the summer while only removing ⅓ will help it stay cool. Grass can actually benefit from being left a little longer in the summer to protect it. If you normally mow at 2.5 inches, try switching to 3 inches in the hot part of the summer.
Be sure your blades are sharp. A dull blade can tear the grass versus a clean cut, allowing the grass to heal quicker and reduce brown appearances.
When it is really hot with drought conditions, hold off on mowing. Mowing causes damage to the lawn and when the lawn is already stressed from dry hot conditions, it can damage the lawn even further. Wait until after rainfall or after watering before mowing.
Fertilizing
You may think fertilizing sounds like a good idea in the summer to keep your grass healthy but that is actually not true. Fertilizer stimulates your lawn to grow which in turn can stress your lawn out during the heat of summer. Wait until Fall to apply your fertilizer so the lawn can recover from summer damage while getting ready for winter. Also avoid aeration and dethatching during the summer as those also cause temporary damage and make it harder for your lawn to recover.
