The end of May and the early part of June is a great time to prepare your lawn for the summer heat and heavy growing period from late June through mid-September. Your lawn will need regular watering during the early morning hours until it feels wet to touch from the surface down about 3-6 inches along with regular mowing at the right height for your specific species of grass. The water and regular mowing helps to strengthen the root growth of your lawn and the deeper the roots grow the better it will handle the high temperatures of summer. When you combine this with weed control and proper fertilization you will be set up for success and a lawn to be proud of all summer long. This time of year, it is recommended for overseeding your lawn to fill in thin and bare spots in the lawn as well in North Carolina.
