Aeration & Overseeding

Core aeration & overseeding for Sheboygan County lawns. The reset button for clay soil.

Our clay-heavy soil packs down a little more every year until water pools, roots suffocate and the lawn thins no matter how much you feed it. Aeration opens the ground back up, overseeding thickens it from the roots down, and compost topdressing rebuilds the soil itself. One fall visit, priced online before anyone comes out.

What we do

Four ways to bring a lawn back, in the order we do them.

Most Sheboygan County lawns want aeration and overseeding in the same visit. Topdressing is the add-on that rebuilds the soil. Hydroseeding is for lawns too far gone to overseed.

Core aerator running across a residential lawn 01

Core aeration

We pull thousands of small soil plugs across the lawn so air, water and fertilizer reach the roots for the first time in years. On our clay it's the single highest-return thing most lawns get all year. Leave the plugs — they break down in a couple of weeks and feed the soil.

  • Every fall on clay
  • Every 2–3 years on sand
  • Plugs stay

Classen overseeder dropping grass seed into an existing lawn 02

Overseeding

Premium cool-season seed spread over the existing lawn straight after aeration, so it drops into the open channels and germinates protected instead of washing off. Thin turf thickens, bare spots close, and weeds lose the open ground they need. We price aerate + overseed as one job.

  • Same visit as aeration
  • Seed drops into the plug holes
  • Water 2–3 weeks
  • Next-season touch-up available

EcoLawn topdresser spreading screened compost across a lawn 03

Compost topdressing — the add-on

A quarter inch of screened compost brushed in right after the plugs come out, so it fills the holes, levels the bumps and rebuilds the soil the new seed has to grow in. Aeration opens the ground; compost is the only thing on this page that adds soil back. We run the only topdresser in Sheboygan County.

  • ¼" screened compost
  • Fills the plug holes
  • Levels bumps
  • 10% off with aeration

Freshly hydroseeded front lawn, green slurry down and ready to germinate 04

Hydroseeding — when overseeding isn't enough

Big bare areas, slopes and lawns being restarted after construction: seed, mulch and starter fertilizer sprayed as one slurry that clings where dry seed washes away. Faster and more even than broadcast seed, a fraction of sod's cost at scale. Priced per property after we see the site.

  • Slopes & bare areas
  • Post-construction lawns
  • Quoted on site
  • Sod alternative

Does my lawn need this?

Five signs the soil, not the grass, is the problem.

If any of these sound like your yard, compaction or thatch is the reason — and no amount of fertilizer fixes a soil problem.

01

Water puddles after rain

Rain sits on the surface or runs off instead of soaking in. The soil is packed too tight to take it.

02

A screwdriver won't go in

Push a screwdriver into the lawn a day after watering. If it stops short, roots are stopping short too.

03

Thin under trees and along walks

Grass that never fills in where feet, tires and shade compact the ground hardest.

04

Moss moving in

Moss wins where grass roots can't breathe. Feeding it more doesn't help; opening the soil does.

05

A spongy thatch mat past half an inch

Dead stems between grass and soil shed water like a thatched roof. We measure it and only dethatch lawns that need it — you'll know on site if yours did.

Questions

Before we pull the plugs.

What homeowners ask us every September.

Ask something else
When should I aerate in Wisconsin?

Early fall — our window runs about Aug 25 to Oct 15, and it's only six weeks long. Soil is warm, weeds are fading, and seedlings get two cool growing months before snow. Spring works as a second choice, but fall-seeded grass establishes with far less weed pressure.

Can I mow and water normally afterward?

Water more, mow less. Keep overseeded areas moist for two to three weeks — about 15–20 minutes daily, split into two shorter cycles on sandy ground — and hold off mowing until the new grass reaches about three inches. We leave you the schedule.

What about the plugs on the lawn?

Leave them. They break down within a couple of weeks and return nutrients to the soil. Raking them up undoes part of the benefit.

Do I need this every year?

High-traffic and clay-heavy lawns benefit annually; sandier or lightly used lawns can go every two to three years. We'll tell you which yours is when we measure.

Aeration or topdressing — which does my lawn need?

Aeration relieves compaction; topdressing rebuilds the soil and levels the surface. If water pools and the ground is rock hard, start with aeration. If the lawn is bumpy and thin, or the soil is sandy and won't hold water, topdressing is the fix. Most Sheboygan County lawns want both in the same fall visit, and we take 10% off the pair. See Lawn Topdressing for pricing.

Do you dethatch every lawn?

No. Only when the thatch mat is past about half an inch — at that point it sheds water and nothing you do after it reaches the soil. We measure first. Skip it in the quote and we'll tell you on site if it was needed.

When is hydroseeding the right choice?

When the area is too large or too bare for overseeding but sod's price tag doesn't make sense — a whole backyard, a slope that sheds seed, or a lawn being restarted after construction. For brand-new lawns, see New Lawn Installation, where hydroseeding sits alongside seed and sod.

How accurate is the online price?

It uses typical turf areas for Sheboygan County and lands within about 10% for most properties. Slopes, tight gate access and heavy tree cover move the number. We measure the actual turf on site and confirm a fixed price in writing before anything is scheduled — valid 30 days, nothing charged until you approve.

Should I fertilize at the same time?

Yes — a fall feeding right after aeration goes straight to the roots through the open plug holes. See Fertilization & Weed Control to pair it.
