Every spring, the same thing happens across Milton, Oakville and Mississauga: the snow finally melts and reveals a matted, brown, debris-covered yard that looks nothing like the lawn you remember. The good news is that grass is resilient — what your lawn looks like in July is largely decided by what you do in April and May. Here's the full reset, in the order that actually works.
First: don't start too early
The most common spring mistake is raking and walking on a lawn that's still soggy from snowmelt. Wet soil compacts under foot traffic, and cold, wet grass crowns snap off when raked. Wait until the lawn has dried out and firmed up — in the GTA, that's typically mid-to-late April, depending on the year. If your footprints sink or stay visible, it's too early.
The 8-step spring cleanup
- Clear debris. Branches, litter and anything winter left behind. This has to come first — everything else works on a clear surface.
- Rake out dead growth and matted leaves. A thorough (but not aggressive) raking lifts matted grass, removes dead material, and lets air and light reach the soil. Watch for grey-pink crusty patches — that's snow mold, and raking it open is exactly the treatment.
- Clean out garden beds. Cut back last year's dead perennials, pull early weeds while they're small, and redefine bed edges for a crisp line.
- Deal with compaction — aerate. Snow load and foot traffic compact soil over winter. Core aeration pulls small plugs out of the lawn so water, air and nutrients reach the roots. Spring and fall are both good windows for it.
- Overseed thin and bare patches. Right after aeration is the perfect moment — seed falls into the holes and germinates fast. Thick grass is also your best weed control: bare spots are where dandelions and crabgrass move in.
- Fertilize — lightly. A balanced spring feeding helps the lawn green up, but heavy nitrogen too early forces weak, leggy growth. Late spring is better than early spring for the first application.
- First mow: keep it high. Set the mower to about 3 inches and never remove more than a third of the blade. Scalping the first cut stresses grass just as it's waking up and invites weeds all season.
- Refresh mulch. Top up beds to 2–3 inches of mulch. It locks in spring moisture, suppresses weeds through summer, and instantly makes the whole property look finished.
How long does it take?
For an average GTA lot, a full spring cleanup done properly is a solid weekend of work for a homeowner — more if beds are extensive or winter was rough. A professional crew with the right equipment does the same job in a few hours, which is exactly why spring is our busiest season. Either way, do it: no other few days of yard work pay off across the whole season like the spring reset.
