Should you aerate before overseeding?
The best time to aerate your lawn is during the fall before you begin a fertilization program or decide to overseed. Run your irrigation system after the turf has been aerated. Aeration will help ensure your soil is ready to absorb all of the nutrients and seeds that come its way with topdressing and overseeding.

With time, the soil will readjust and close the small holes you made in the ground.
