The best time to aerate your lawn is in the fall, typically between September and November. This is the optimal time because the grass is actively growing, allowing the soil to recover and new grass to establish itself before the winter months.
Aerating your lawn helps to alleviate soil compaction, which can occur due to heavy foot traffic, lawn mowers, and other factors. By creating small holes in the soil, aeration allows air, water, and nutrients to better penetrate the roots, promoting healthier and more vibrant grass growth.
