Gravity, foot traffic, lawn mowers, and rainfall cause soil to become compacted over time. Aeration helps control thatch, improves the soil structure, helps create growth pockets for new roots, and opens the way for water and fertilizer to reach the root zone of your lawn
For best results, it is generally a good idea to aerate the soil before seeding. This will create a seed bed by loosening the soil with the aeration, thus allowing the most “seed to soil” contact, which is crucial to seed germination.
For those unfamiliar with core aeration, this is the same service that is performed on golf course greens. It is a process which extracts “plugs” of existing soil and deposits them on the surface of the lawn.
Aeration relieves soil compaction allowing grass roots to expand and proper drainage of the soil.
