ServiCover📌 Key Takeaway: Core aeration typically costs $75-$200, while seeding or overseeding ranges $440-$1,750 depending on lawn size and seed. For cool-season grasses, early fall is usually the best time for both.
Why Aerate?
Foot traffic, mowing and clay soils compact the ground, making it harder for water, air and nutrients to reach roots. Aeration pulls small plugs of soil to open channels, and it creates ideal pockets for new seed to take hold.
Core vs. Spike Aeration
| Type | How It Works | Effectiveness |
|---|---|---|
| Core (plug) aeration | Removes small soil cores | Relieves compaction — the professional standard |
| Spike aeration | Pokes holes without removing soil | Can add compaction around holes; less effective |
Best Timing by Grass Type
| Grass Type | Examples | Best Time |
|---|---|---|
| Cool-season | Kentucky bluegrass, fescue, ryegrass | Early fall (spring as a second choice) |
| Warm-season | Bermuda, zoysia, St. Augustine | Late spring to early summer |
Aftercare
- Leave the soil plugs — they break down within a couple of weeks.
- Water new seed lightly and often until it germinates.
- Hold off on mowing new grass until it reaches normal mowing height.
- Avoid pre-emergent weed killers that can stop new seed from sprouting.
Frequently Asked Questions
How often should I aerate?
Many lawns benefit from yearly aeration, especially with heavy traffic or clay soil. Sandy, low-traffic lawns may need it less often.
Can I aerate and fertilize at the same time?
Yes — fertilizing after aeration can help nutrients reach the root zone, and many companies bundle the two.
