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 Cornwall's steep, shaded ground is the hardest we work

Cornwall is mountain country by Connecticut standards — steep wooded hillsides, the Housatonic cutting through, and elevations that make it one of the coldest corners of the state. Most properties here are clearings in forest rather than lawns with trees around them, which puts turf up against dense canopy, surface roots and very little direct sun for much of the day.

The soil does not help. It is thin, stony and often sits directly on ledge, and on a pitch that steep it never accumulates. Add the shortest growing season we work in and the margin for error narrows considerably — seed that goes down late simply does not establish before the cold. Core aeration is worth doing because the top two to three inches is effectively the whole root zone here, and overseeding into the holes is the only reliable way to get seed to hold on sloping ground. We weight the blend heavily toward fine and turf-type tall fescues for the shade tolerance. And where the canopy has closed over entirely, we will say so — there are Cornwall properties where a woodland edge serves better than a lawn.

Common questions

When does the window close up here?

Earlier than anywhere else we work. Late August into early September is the target; by October the soil is generally too cold for seed to establish before winter.

Is it worth it under heavy shade?

Sometimes not, and we will tell you. Below roughly four hours of filtered light, grass loses regardless of blend or aeration. A shade planting or woodland edge is the honest answer in those spots.

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.
