In Quebec: light raking and a first fertilizer in spring, mowing at 8 cm all summer while leaving clippings in place, grub prevention from mid-August to mid-September, aeration and overseeding in late summer, then a fall fertilizer and a slightly shorter last mow before snow.
The calendar
| When | What to do |
|---|---|
| Late April to May | Light raking, winter damage repair, first fertilizer, aeration if soil has drained |
| May to June | Mow at 8 cm, weed control, possible overseeding |
| July | Mow high, deep but infrequent watering if needed, scout for chinch bugs |
| Mid-August to mid-September | Grub prevention, aeration, top-dressing, overseeding |
| September to October | Fall fertilizer, mulch leaves with the mower |
| Late October to November | Last mow, stay off frozen grass |
All-season habits
- Mow high, around 8 cm, never removing more than a third at once.
- Grasscycling: leave clippings on the lawn as free fertilizer.
- Water deeply and less often, following your city’s watering rules.
- Check pH: most lawns do best between 6 and 7.
