The answer to 'best time for aeration' is that the best time to aerate your lawn is in the fall, typically between September and November. Aerating your lawn during this time of year allows the soil to recover and prepare for the upcoming growing season.
Aerating your lawn helps to alleviate soil compaction, which can prevent water, air, and nutrients from reaching the roots of your grass. By creating small holes or plugs in the soil, aeration allows these essential elements to penetrate the ground more easily, promoting healthier, more robust grass growth.
