How Often Should You Mow Your Lawn in Ontario? A Seasonal Guide for Homeowners
Understanding Ontario's Growing Seasons
Ontario's climate is unique, with distinct growing seasons that affect how often you should mow your lawn. Typically, the lawn mowing season in Ontario spans from late April to mid-October. Understanding these seasonal changes can help maintain a healthy and attractive lawn.

Spring: Kickstart Your Lawn Care
As the temperatures rise in late April and May, grass begins to grow rapidly. During this period, it's crucial to mow your lawn about once a week. Regular mowing helps prevent stress on the grass by not cutting more than one-third of the grass blade at a time. This promotes healthier growth and a luscious green appearance.
Summer: Adapting to Heat and Drought
Summer in Ontario can be warm, and sometimes dry, which affects grass growth. It's usually recommended to mow every 1 to 2 weeks, depending on rainfall and growth rate. During hot spells, raise your mower blades slightly to leave the grass longer, providing shade for the soil and reducing water evaporation.

Fall: Preparing for Winter
As fall arrives, grass growth slows down. However, it's important to continue mowing to keep your lawn neat and healthy. Mow every 1 to 2 weeks until the first frost. Gradually lower the cutting height towards the end of the season to prevent mold and disease during the winter months.
Winter: Time for a Break
Once the ground freezes, your lawn care routine can take a pause. Mowing isn't necessary during winter, as grass is dormant. Use this time to maintain your mower and prepare for the next growing season.

Tips for Effective Lawn Mowing
To ensure your lawn stays in optimal condition, consider these tips:
- Sharpen Your Mower Blades: Dull blades tear grass rather than cut it, leading to a ragged appearance and increased susceptibility to disease.
- Mow When the Grass is Dry: Wet grass can clump and cause uneven cuts.
- Vary Your Mowing Pattern: Change directions each time you mow to prevent soil compaction and promote upright growth.
The Importance of Regular Maintenance
Mowing is just one aspect of lawn care. Regular maintenance, including watering, fertilizing, and aerating, plays a crucial role in keeping your yard healthy. By following this seasonal guide, you can ensure your lawn remains vibrant and well-maintained throughout the year.
