What's Included

Core aeration

We pull thousands of soil plugs to open compacted clay and rocky loam, so air, water and nutrients reach the root zone.

Premium overseeding

Turf-Type tall fescue and Kentucky bluegrass blend, A-List blue-tag varieties, dropped straight into the aeration holes.

Fall timing

Cooler air and fall moisture give new seed its best window to establish before winter and root deeply going into the cold.

Marked before we arrive

Aeration reaches 2 to 3 inches, so irrigation heads and lines, low-voltage wiring and invisible fences need marking first. Most customers mark their own — we can do it for a fee if you'd rather.

Not sure whether your lawn needs it this fall? We'll walk the property and give you a straight answer — including if the timing's wrong.

Why Washington lawns sit on some of the stoniest ground in the state

Washington covers high ground above the Shepaug, and the land here has been worked and grazed for centuries without ever becoming easy. The soil is classic Litchfield till — stone all the way through, shallow over ledge on the ridges, and tight enough when it dries that a spade argues back. The stone walls running through the woods are there because the fields had to be cleared before anything would grow, and the ground has not changed since.

Lawns on that soil face two limits at once: not much depth, and a profile that closes up under any traffic. Roots run out of room quickly, so August is unforgiving in a way it is not on deeper valley ground. Core aeration is worth doing precisely because it works the depth that exists rather than assuming more, and on stony ground the plugs come up short in places, which is normal here. Overseeding into the holes builds the density that shades the soil and holds moisture at the crown. We weight the blend toward turf-type tall fescue for the deepest rooting a shallow profile allows.

Common questions

Will the tines just hit stone?

Some will, and that is normal on Washington ground. You get shorter plugs in places and the machine works around what it finds. It does not stop the treatment doing its job on the soil that is there.

Does the elevation affect timing?

Yes — the warm-soil window closes earlier up here than in the valley towns, so we aim for late August into September rather than pushing toward mid-October.

Who marks the irrigation and invisible fence?

You do — or we can, for a fee. Aeration reaches two to three inches, so anything shallow needs marking first.
