How to Mow for a Thicker, Healthier Lawn This Spring in St. Catharines
Mowing your lawn might seem like the most basic part of lawn care — but doing it right can actually make or break your lawn’s health. The way you mow in spring sets the tone for the entire growing season.
At Don’s Lawn & Land Care, we help homeowners across St. Catharines achieve thick, vibrant lawns by focusing on small details that deliver big results. Here’s how to mow smarter this spring.
1. Don’t Mow Too Early
Your lawn needs time to recover from winter dormancy. Mowing too soon can stress grass that hasn’t fully greened up yet.
✅ Wait until your grass is actively growing and at least 3 inches tall before the first cut.
2. Follow the ⅓ Rule
Never remove more than one-third of the grass blade in a single mowing. Cutting too short stresses the plant, exposes the soil, and encourages weeds to move in.
If your lawn is 3 inches tall, mow no shorter than 2 inches.
Cutting too much at once can also lead to brown tips and weak root systems.
3. Set the Right Mower Height
For most cool-season grasses common in St. Catharines (like Kentucky bluegrass or fescue), the ideal mowing height is 2.5 to 3.5 inches.
Higher mowing:
Shades the soil, reducing weed germination.
Helps retain moisture.
Promotes deeper roots and stronger turf.
4. Keep Your Mower Blades Sharp
Dull blades tear the grass instead of cutting it cleanly, leading to:
Frayed edges that turn brown.
Increased disease vulnerability.
A rough, unhealthy appearance.
Sharpen your blades at least once every spring — or more often if you mow frequently.
5. Leave Grass Clippings
Mulching your clippings returns nutrients to the soil and reduces the need for fertilizer. Let those clippings work as free, natural fertilizer!
Bonus Tip: Vary Your Mowing Pattern
Mowing in the same direction every time can compact the soil and cause ruts. Change up your mowing pattern weekly to encourage upright growth and reduce wear on the lawn.
