Summer is when lawns often appear to be at the height of health. This doesn't mean it is time to sit back and relax, though. Caring for your lawn properly all through the summer ensures it doesn't just remain green, but that it receives all it needs to maintain the healthy roots necessary for winter survival. The heat of summer often requires additional water for the lawn, as well as continued fertilizer feedings to keep it looking its best. Proper summer lawn care ensures your lawn enters the fall looking its best.
Water the lawn regularly during the summer, providing approximately one inch of water in a single weekly watering. Leave sprinklers on for one to two hours per each lawn area so the soil is moist to an eight-inch depth.
Fertilize the lawn in early summer with a nitrogen-rich lawn fertilizer. Apply approximately two pounds of fertilizer per 1,000 square feet of lawn, following label instructions for exact application amounts. Slow-release fertilizer is most beneficial in summer.
Maintain a mowing height of three to 3.5 inches. Higher grass preserves more moisture in the soil while also developing deeper roots, which leads to a more drought-tolerant and healthy lawn.
Mow lawns in the early morning or evening hours when temperatures have cooled. Mowing in the heat of the day places stress on the lawn and may lead to burning or browning.
