In Northeast Ohio, September is the best time to work on lawn health (April is the second-best time). Whether you need to patch, repair, over-seed, or completely start over and re-seed, starting a new lawn in fall or spring is best. Soil temperatures are warm, air temperatures are cool, and natural rains during these seasons support proper irrigation. When seeding the lawn, it helps to study your site, test soil pH for potential amending, select quality seed, and use starter fertilizer.
