Spring lawn with aeration cores on a vibrant green Canadian yard

When frost is gone and soil is workable, core aerate compacted areas to improve root oxygen. For cool-season grasses common in Canada (Kentucky bluegrass, fescue, rye), set your first mow high at 7.5–9 cm to protect crowns during spring swings.

  • Water lightly after aeration to help soil cores break down.
  • Topdress thin spots with 0.6 cm compost for organic matter.
  • Sharpen blades for a clean cut and reduced disease.

Water deeply and infrequently: aim for 2.5 cm per week, delivered in 1–2 sessions to encourage deep rooting. Water at dawn to reduce evaporation and disease risk.

  • Use a rain gauge or tuna can to measure 2.5 cm.
  • Pause irrigation after heavy rainfall to save water.
  • Adjust for clay vs. sandy soils—split sessions if runoff occurs.

Raise mowing height to 9–10 cm during heat to shade soil and reduce stress. Use temporary shade cloths for new seed and avoid fertilizing in peak heat.

  • Leave clippings to mulch and retain moisture.
  • Spot-water hot spots to prevent dormancy.
  • Avoid heavy traffic on stressed turf.

Late summer to early fall is prime time to overseed cool-season lawns. Soil is warm, nights are cooler, and weeds are waning—perfect for establishment.

  • Slice seed after dethatching for better seed-to-soil contact.
  • Keep seedbed consistently moist for 10–14 days.
  • Blend cultivars for disease resistance and colour.

Avoid piling salted snow on turf. Use calcium magnesium acetate or sand near edges, and let an even snow cover insulate crowns through freeze–thaw cycles.

  • Mark driveway edges to keep plows off turf.
  • Final mow at 5–6 cm to reduce snow mold risk.
  • Keep foot traffic to paths to prevent crown damage.

Prioritize organic matter with screened compost topdressing. If using fertilizer, choose slow-release, low-nitrogen formulas to minimize runoff into Canadian waterways.

  • Target 0.5–1 cm compost across the lawn in spring.
  • Soil test every 2–3 years to fine-tune inputs.
  • Blow granules off hard surfaces to prevent storm-drain pollution.

Mulch mow leaves into confetti that filters between blades—free nutrients and organic matter. Neaten edges before ground freezes for a tidy winter look.

  • Multiple passes reduce leaf size; avoid thick mats.
  • Compost excess leaves; mix with grass for balance.
  • Trim perimeters at 5–6 cm for winter health.
