The Complete Spring Lawn Care Checklist for Guelph Homes
Spring lawn care isn’t complicated, but the order matters. Aerate before cleanup and you punch cores through a mat of dead leaves. Fertilize before the grass wakes up and you feed the weeds instead. This is the sequence we run across our Guelph routes every April and May.
1. Wait for the ground to firm up
Nothing on this list should happen while the soil is saturated. Foot traffic and equipment on soggy turf cause compaction that lasts the whole season. In Guelph that usually means holding off until mid-to-late April.
2. Spring cleanup
Rake or blow out leaves, branches and winter grit (Guelph road sand ends up surprisingly deep into front lawns). Rake matted, grey patches of dead grass while you’re at it — snow mould thrives under matted turf, and opening it up lets the crowns breathe and regrow.
3. First cut at the right height
Once the grass hits about 4 inches, cut back to 3. Sharp blade, dry lawn. See our guide on when to start mowing in Guelph for the two tests we use.
4. Overseed thin areas
Spring overseeding works if you get seed down early enough to establish before summer heat. Rough up bare patches, seed, and keep them consistently damp. For whole-lawn thickening we usually recommend waiting for early September — germination rates are dramatically better.
5. Fertilize once the lawn is actively growing
Late May into early June is the spring window here — after the natural spring flush, not before. Feeding too early pushes soft top-growth the lawn can’t sustain.
6. Edge, mulch and reset the beds
A crisp spade edge and a fresh 2–3 inches of mulch does more for curb appeal than anything else on this list, and mulched beds hold moisture through summer while suppressing weeds.
