Summer’s heat can often be stressful for area lawns. According to Iowa State University Extension and Outreach horticulturists, Kentucky bluegrass yards should be mowed at a height of three to three-and-a-half inches in the summer and about half an inch shorter in the spring and fall. By allowing it to grow in the summer, it helps shad and cool the crowns of the turfgrass plants and provides more food-producing foliage while promoting deeper root growth.

Also, it is advised when mowing the lawn, never remove more than one-third of the total leaf area at once, as it injures the turfgrass plants and reduces their ability to withstand environmental stresses.
