The Best Time to Aerate and Overseed Your Lawn in Ohio

The best time to aerate and overseed a lawn in Ohio is early fall — roughly late August through September. Warm soil, cooler air, and fall moisture give new grass the ideal window to germinate and establish before winter.

Why fall beats spring

Fall seeding avoids spring's crabgrass competition and summer heat stress. The soil is still warm enough for fast germination, and young grass gets two cool growing seasons — fall and the following spring — to mature before its first summer.

Why aerate and overseed together?

  • Aeration pulls plugs from compacted clay soil, opening it up for air, water, and roots.
  • Overseeding right after drops seed into those holes for great soil contact.
  • A fall fertilizer feeds the new grass and the rest of the lawn.
