Aeration & Overseeding
The most impactful thing you can do for a compacted, thin, or struggling lawn — core aeration and overseeding opens the soil, improves drainage, and fills in bare areas with fresh, dense turf.
The Foundation of a Thick, Healthy Lawn
Over time, soil compaction, thatch buildup, and normal wear thin out even well-maintained lawns. Core aeration relieves compaction by pulling small plugs of soil from the ground, allowing air, water, and nutrients to penetrate deeply. Paired with overseeding, it's the most effective way to thicken your lawn, improve root depth, and set the stage for a stronger growing season.
Why Aeration & Overseeding Works
Relieves Soil Compaction
Compacted soil suffocates grass roots and prevents water and nutrients from reaching the root zone. Core aeration breaks up compaction and restores healthy soil structure.
Reduces Thatch Buildup
A thin layer of thatch is normal, but excessive buildup blocks water and air movement. Aeration disrupts the thatch layer and accelerates its breakdown by soil microbes.
Improves Water & Nutrient Uptake
Open channels in the soil allow fertilizer, water, and oxygen to reach the root zone more efficiently — making every other treatment you invest in more effective.
Thickens Thin or Bare Areas
Overseeding immediately after aeration places seed directly into the aeration holes, giving new grass the soil contact and moisture retention it needs to germinate and establish.
Improves Drought & Stress Tolerance
Deeper roots developed after aeration give your lawn better access to moisture stored lower in the soil profile, improving resilience through dry spells and heat stress.
Enhances Overall Lawn Density
A denser turf canopy naturally crowds out weeds, resists disease, and recovers faster from traffic and wear — compounding the benefits of your entire lawn care program.
What to Expect
Pre-Service Preparation
Continue mowing at your normal height — no need to cut shorter than usual. We recommend flagging sprinkler heads, underground dog fences, and any known shallow cables or buried objects before your service.
Core Aeration
A core aerator pulls 2–3 inch plugs of soil across the entire lawn. These plugs are left on the surface to break down naturally, returning organic matter to the soil.
Overseeding
Premium grass seed is spread immediately after aeration, falling into the holes for excellent seed-to-soil contact. Seed variety is selected to match your existing turf and site conditions.
Post-Service Care
Watering after overseeding helps seed germinate and establish — if your lawn has irrigation or you're able to water regularly, aim for light, consistent moisture over the first 2–3 weeks. No irrigation? No problem. Fall rains and natural moisture do a great job supporting germination this time of year. We'll walk you through aftercare so you get the most out of your investment.
Best Time to Aerate & Overseed in Michigan
Late summer through early fall — typically late August through September — is the ideal window for aeration and overseeding in Washtenaw County. Soil temperatures are still warm enough for germination, cooler air reduces heat stress on new seedlings, and fall rains help keep seed moist. Spring aeration is also available for lawns with severe compaction issues.
