Much of Guelph — especially the newer subdivisions in Westminster Woods, Clairfields and Kortright East — sits on heavy clay that compacts hard under a season of mowing, kids and dogs. Water starts running off instead of soaking in, roots suffocate, and the lawn thins no matter how much you water and feed it.
Core aeration fixes the cause: we pull thousands of soil plugs from the lawn so air, water and nutrients reach the root zone again. Overseeding immediately after drops fresh seed into those holes — perfect seed-to-soil contact — and thickens the lawn with improved grass varieties.
What's Included
When to aerate in Guelph
Early September is the gold-standard window: warm soil germinates seed fast, cool air and fall rain establish it, and the lawn heads into winter thicker than it started. Spring is a solid second choice for compacted lawns that can’t wait. Midsummer aeration on a dry lawn does more harm than good — a company that pushes it in July is selling a route slot, not a result.
Not sure you need it? Try the screwdriver test: push a screwdriver into the lawn a day after rain. If you have to force it, your soil is compacted. If it slides in easily, spend the money on overseeding or fertilizer instead — and yes, we’ll tell you that at the quote.
