What's Included

Two steps that work best together.

🕳️

Core Aeration

We pull thousands of soil plugs across your lawn, opening up compacted ground so air, water, and nutrients reach the roots.

🌾

Overseeding

Fresh turf-type tall fescue spread across the lawn, plus starter fertilizer to feed new seedlings. Seed settles into the open holes for real soil contact — that's where germination happens.

Why Aerate and Overseed?

If you only do one thing for your lawn this year, this is it — and fall is the window.

🌱

A Thicker Lawn

New grass fills in the thin spots.

Fresh seed dropped into open aeration holes gives you a denser lawn next spring — not just a green one.

🧱

Beats Kansas Clay

Compaction pulled out by the plug.

Our heavy clay soil packs down hard every summer. Core aeration physically removes plugs so roots have room to grow again.

💧

Water Actually Soaks In

Less runoff, deeper roots.

Instead of running off compacted ground, water and fertilizer reach the root zone where they do some good.

🌾

Quality Seed

Turf-type tall fescue built for Kansas.

We use a blend chosen for our transition-zone summers — not the cheapest bag on the shelf.

🍂

Right Time of Year

Fall is the window that works.

Late August through October gives new seed warm soil and cool air to establish before winter. Spring seeding rarely survives our summer.

After We're Done

What happens next is up to you — and one thing matters more than everything else combined.

Crucial — don't skip this

The seed must stay damp for two full weeks

This is the whole ballgame. Grass seed only germinates while it's consistently moist — and once a seed starts to sprout and then dries out, it dies and it does not come back. A lawn that gets watered and one that doesn't are two completely different results from the same job.

Water lightly every day for the first two weeks — enough to keep the top inch damp, twice a day if it's hot or windy. Short and frequent beats one long soak, which just runs off and carries seed with it. After you see germination, back off to less frequent, deeper watering.

Leave the Plugs

Those soil plugs on your lawn break down on their own in 2–3 weeks. Don't rake them up — they're feeding the lawn back.

Mow High, Wait to Treat

Mow at 3–4" and hold off on weed control until new grass has been mowed a few times — herbicide kills baby grass too.

What Our Customers Say

The crew did a great job! They were able to come within the same day of the request and had all of the leaves cleaned up in less than 30 minutes or so! Very appreciative of their work.

Prompt response and very punctual in completing the work requested. Cayden was extremely helpful in squeezing the job in on the Holiday week of Thanksgiving. Highly recommend the lawn service!!!

John Peter S.

My mower needed servicing, and Sommer Lawn was recommended. I'm sticking with them through the rest of the year! Saves me a lot of time every week, and I love the sharp edging.
