Month‑by‑Month Lawn Care Guide for Saskatoon

Homeowners in Saskatoon, Martensville, and Warman get the best lawn results when they time tasks to local weather patterns and growing stages. This month‑by‑month guide builds on your outline and keeps things original while aligning with Prairie conditions.

Early Spring (March–April)

As snow melts and the ground firms up, lightly rake away leaves, sand, and dead grass so new shoots can push through without tearing tender roots in soggy soil. This is also the time to walk the yard, mark bare or damaged spots, and start planning overseeding and fertilizing for later in spring, once the lawn is clearly growing again.

Hold off on heavy work such as aeration or rolling until the soil has dried and you are not leaving footprints or ruts, which can worsen compaction. Use this window to clean up edges, check your irrigation, and service your mower so it is ready with a sharp blade for the first cut.

Late Spring (May–June)

Once the lawn has greened up and growth is steady, start regular mowing at about 2.5–3 inches (5–9 cm), staying within the one‑third rule so you are never removing too much at once. This height helps shade the soil, reduce weed pressure, and support deeper roots going into the warmer months.

Late spring is also prime time to overseed thin or bare areas and apply a spring fertilizer combined with early‑season weed control to help the grass fill in before summer stress arrives. Water newly seeded spots gently but consistently to keep the top layer moist until seedlings are established.

Summer (July–August)

During the hottest part of the season, focus on moisture management and stress reduction rather than major renovation work. Water deeply but infrequently, aiming for roughly 2.5 cm (1 inch) of total water per week from rain and irrigation, and consider raising your mowing height slightly to offer extra shade and root protection.

Keep an eye out for signs of heat or drought stress, such as footprints that linger or bluish‑grey patches, and adjust watering accordingly. Avoid heavy fertilizing or aggressive weed treatments during extreme heat, since stressed grass is more prone to burning and damage.

Fall (September–October)

As temperatures cool but soil remains warm, early fall becomes the ideal window for core aeration and overseeding to relieve compaction and thicken the lawn before winter. Aeration opens channels for air, water, and nutrients, while overseeding introduces new, vigorous plants that can fill in thin areas.

A final fertilizer application around early to mid‑September helps strengthen roots and improve winter hardiness without forcing late, tender growth. Continue mowing until growth slows, gradually lowering the height slightly for the last cuts while still avoiding scalping before snow arrives.
