In addition to mowing, fertilizing and watering, it is important to ensure nutrients can reach the soil beneath your grass. Core aeration helps alleviate soil compaction which allows air and water to penetrate built-up grass or lawn thatch that can starve the roots from essential nutrients.
Core aeration perforates the soil with small holes to allow air, water, and nutrients to penetrate the grass roots, which helps the roots grow deeper and produce a stronger, more vigorous lawn.
The best time for aeration is during the growing season when the grass can heal and fill in any open areas after soil plugs are removed. Fall is a great time to core aerate your lawn!
