How Often Should I Mow My Lawn?

Keeping your lawn healthy and lush in Edmonton isn’t just about watering and fertilizing—it’s also about mowing at the right frequency. Mowing too often or not enough can stress the grass, making it more prone to weeds, disease, and poor growth.

In this guide, we’ll explain how often you should mow your lawn, why frequency matters, and how to adjust your mowing schedule throughout the season.

The General Rule: The One-Third Rule

A healthy lawn should never have more than one-third of its blade height removed in a single mowing. This is known as the one-third rule—and it’s the foundation for determining how often you mow.

• If your grass is growing quickly (such as in spring), you may need to mow every 4–5 days.
• During slower growth periods (summer heat or drought), you might mow once every 7–10 days.

Tip: Different grass types grow at different speeds. In Edmonton, common varieties like Kentucky bluegrass and perennial ryegrass often need weekly mowing in peak season.

Seasonal Mowing Guide for Edmonton Lawns

Spring (April–June)

Spring growth is fast thanks to longer daylight hours and regular rain. Expect to mow more often—sometimes twice per week in May if conditions are ideal.

• Maintain a height of 2.5–3 inches.
• Use a sharp blade to avoid tearing grass tips.

Summer (July–August)

Hotter, drier weather slows growth. Mowing too short can stress your lawn and make it more vulnerable to weeds like quackgrass.

• Mow every 7–10 days.
• Keep grass taller—3–3.5 inches—to retain soil moisture.

Fall (September–October)

Cooler temperatures bring a final growth spurt before dormancy. Continue mowing regularly until the grass stops growing.

• Drop the height slightly to 2.5–3 inches for winter prep.
• Avoid cutting too short before the first frost.

Why Mowing Frequency Matters

Mowing at the right interval:

• Encourages thick, healthy turf
• Reduces weed competition
• Improves drought resistance
• Enhances curb appeal year-round

Cutting too much at once can shock your lawn, while letting it grow too long can smother lower blades and invite pests.
