Lawn Mowing in Fort McMurray: The Exact Schedule and Height for Our Climate

Written by Team GrassDocs | Dec 29, 2025 9:54:53 PM

Quick Answer: How Often Should You Mow in Fort McMurray?

In Fort McMurray’s short, cool growing season, a healthy lawn usually needs:

  • Start mowing: Late May to early June, when grass is actively growing
  • Peak season (June–August): Mow once per week
  • Spring & fall: Mow every 10–14 days, depending on growth
  • Ideal mowing height: Keep grass at 2.5–3 inches (6–7.5 cm)
  • Last mow of the year: Late September to early October, before hard frost and lasting snow

What Makes Lawn Mowing in Fort McMurray Different?

Fort McMurray has a cool, northern climate:

  • Long, cold winters and late springs
  • A short growing season
  • Cool nights even in summer, which slow grass growth

Because of this, copying mowing advice from warmer regions doesn’t work well here. You need a schedule that matches our weather.

What Is the Best Mowing Height in Fort McMurray?

Q: What height should I mow my lawn in Fort McMurray?

For most cool‑season grasses common here (like Kentucky bluegrass and fescues), aim for:

  • 2.5–3 inches (6–7.5 cm) during the main growing season

Why this height works best in our climate

  • Protects roots from temperature swings
  • Shades the soil, helping it stay moist
  • Reduces weed pressure by crowding out weed seedlings
  • Helps recovery after our long winter and late snowmelt

Important rule: Never cut off more than one‑third of the grass blade at a time. If your lawn is very long, raise the mower and bring it down in two cuts over a few days instead of one very short cut.

Fort McMurray Mowing Schedule: Month‑by‑Month

1. Spring: Late May to Early June

Q: When should I start mowing in Fort McMurray?
A: Start when:

  • The ground is firm, not soft or muddy from melt
  • Grass is about 3.5–4 inches (9–10 cm) tall

Spring mowing guidelines:

  • Frequency: Every 10–14 days at first
  • Mower height: About 3 inches (7.5 cm)
  • Goal: Light, gentle cuts to help the lawn wake up after winter

2. Summer: June to August (Peak Growing Season)

This is your main mowing window.

Q: How often should I mow in summer in Fort McMurray?
A: Plan to mow once per week in June, July, and early August.

Summer mowing guidelines:

  • Frequency: About weekly, adjusting if growth speeds up or slows down
  • Height: Keep grass at 2.5–3 inches (6–7.5 cm)
  • Best time of day: Morning or early evening, not in peak heat

If we get a stretch of heat or dry weather:

  • Raise the blade slightly (closer to 3 inches)
  • Do not mow very short to “stretch out” time between cuts—short grass dries out and stresses easily

3. Fall: September to Early October

Growth slows, but your lawn is still active.

Q: How should I mow my lawn in the fall in Fort McMurray?
A: Gradually reduce mowing frequency and slightly lower your cutting height.

Fall mowing guidelines:

  • Frequency: Every 10–14 days, depending on growth
  • Height: Around 2.5–2.75 inches (6–7 cm)
  • Last cut: Late September to early October, before the ground freezes and snow stays

A slightly shorter final cut helps reduce snow mould and matting over winter, but avoid scalping.

Watering to Support a Healthy Mowing Routine

Q: How should I water my lawn to match this mowing schedule?

In Fort McMurray, think deep and infrequent:

  • Aim for about 1 inch (2.5 cm) of water per week in dry stretches
  • Water early in the morning so blades dry during the day
  • Avoid shallow, daily watering that only wets the top of the soil

Deep watering encourages deep roots, which:

  • Survive temperature swings better
  • Stay greener between rains
  • Recover more quickly after mowing

Fertilizing and Overseeding for Stronger, Easier‑to‑Mow Lawns

Q: When should I fertilize my lawn in Fort McMurray?

A simple local‑friendly pattern:

  • Late spring: Light feeding once grass is actively growing
  • Late summer/early fall: Another application to help recovery and winter prep

Overseeding thin areas in late spring or late summer helps:

  • Thicken the lawn
  • Fill bare spots
  • Reduce weeds long‑term

A healthier, thicker lawn:

  • Needs less rescue work
  • Responds better to your mowing schedule
  • Looks greener with fewer inputs

Common Lawn Problems in Fort McMurray (and How Mowing Fixes Them)

Q: Why is my lawn patchy after winter?

Possible reasons:

  • Winter damage, snow mould, or traffic on frozen turf
  • Compacted soil from snow and melt

What to do:

  • Keep mowing height at around 3 inches in spring
  • Overseed thin spots
  • Avoid cutting too short while the lawn is recovering

Q: Why do I have so many weeds, even when I mow?

If you mow too short or too infrequently, you create perfect conditions for weeds.

Fix it:

  • Stick to weekly mowing in peak season
  • Keep the mower at 2.5–3 inches
  • Make sure blades are sharp so they cut cleanly instead of tearing

Q: Why do the tips of my grass look brown after mowing?

This usually means dull mower blades.

Solution:

  • Sharpen mower blades at least once per season, ideally more for heavy use
  • Avoid mowing when grass is wet, which tears instead of cutting cleanly
