Lawn aeration in Blainville, Sainte-Thérèse and Mirabel
A yellowed lawn that drains poorly, or one that's grown dense and compacted? Mechanical core aeration reopens the soil so water, oxygen and fertilizer can finally reach the roots again.
Why aerate your lawn
Over time, repeated mowing, normal yard use and the heavy clay soil typical of our region all compact the ground. Roots run short of oxygen, water runs off instead of soaking in, and the lawn loses vigour — even if you water and fertilize on schedule.
Mechanical aeration pulls small cylinders of soil ("cores") at regular intervals, reopening the ground. It's one of the most effective treatments for bringing a tired lawn back.
The right window in the season
In Quebec, the best windows to aerate are spring (late May – early June) once the soil has fully thawed, or late summer / early fall (late August – September). The lawn recovers best at these times, and new roots take immediate advantage of the openings.
Aeration plus post-aeration fertilizing is the classic combo — fertilizer drops straight into the holes instead of sitting on the surface.
How it works
Our crews bring a mechanical core aerator. We cover the whole lawn in a few minutes depending on size. The cores are left on the lawn — they break down with the first rains and feed the grass.

Frequently asked questions
When is the best time to aerate?
Spring (late May to early June) or early fall (late August to September). Avoid heatwaves and droughts — the lawn doesn't recover well without moisture.
How often should I aerate?
Once a year or every other year is enough for most residential lawns. Heavily-used lawns (pets, kids) or those on clay soil benefit from a yearly pass.
Why leave the cores on the lawn?
The soil cylinders break down within a few days under rain or watering and return their nutrients to the lawn. Removing them would be both unnecessary and costly.
Should I fertilize after aeration?
Yes — it's the ideal moment. The holes left by the aerator let fertilizer reach the roots directly, making the treatment significantly more effective.
