Winter may seem like the season to forget about lawn care, but beneath the surface, your grass is going through a crucial hibernation process. Understanding how your lawn behaves in the winter and how environmental factors like freeze/thaw cycles and lack of snow cover affect it can help you prepare for a healthier spring lawn.
What Happens to Your Lawn in the Winter?
1. Dormancy
During winter, your lawn enters a state of dormancy. “When grass goes dormant for the winter, it shuts down and turns brown to save water and nutrients.” (City of Calgary)
Grass stops growing and focuses on conserving energy to survive the cold months. This is a natural process and doesn’t mean your lawn is dead—it’s simply resting.
2. Impact of Freeze/Thaw Cycles
Alberta winters often bring freeze/thaw cycles, especially during chinooks in the Calgary area. These temperature fluctuations can stress your grass, causing the soil to heave and potentially damage the roots. Without a blanket of insulating snow, the lawn is more vulnerable to these changes.
3. Moisture Challenges
While snow provides a natural water source, lawns without snow cover can become dry. Winter winds and fluctuating temperatures can dry out the grass blades, leading to potential winterkill.
Tips to Protect Your Lawn During Winter
1. Encourage Snow Cover
Snow acts as a natural insulator, protecting your lawn from extreme temperatures. Avoid removing all snow from grassy areas unless necessary.
2. Prevent Freeze/Thaw Damage
Minimize foot traffic during freeze/thaw cycles to avoid stressing the grass and soil.
By understanding what happens to your lawn during winter and taking proactive steps, you can reduce damage and prepare your lawn for a thriving spring season.
