Aeration & overseeding in Guelph
Compacted soil chokes a lawn from below. Core aeration opens it up — and overseeding fills it in.
Give the roots room to breathe
Guelph’s clay-heavy soils compact easily under foot traffic, rain and time. Core aeration pulls small plugs of soil from the lawn so water, air and nutrients can actually reach the roots — the single best mechanical treatment for a tired lawn.
- Relieves compaction so roots grow deeper
- Improves water absorption and drainage
- Best in spring or early fall while grass is actively growing
- Plugs break down naturally within a couple of weeks

Aeration’s perfect partner
Right after aeration is the best possible moment to overseed: the open holes give seed direct soil contact, so germination rates jump. New grass fills thin patches and crowds out the weeds that need bare soil to take hold. Pair it with a fall fertilizer application and you’ve set up next spring’s lawn before winter even arrives.
