As autumn settles over York Region, your grass is actively storing energy, nutrients, and moisture in preparation for the harsh winter months ahead. What you do between September and November determines whether your lawn emerges in May lush and resilient—or patchy and plagued by snow mold.
1. Core Aeration & Overseeding
Compacted soil from summer foot traffic restricts oxygen and water from reaching grass roots. Core aeration pulls small soil plugs to relieve compaction, allowing nutrients and late-fall moisture to penetrate deep into the root zone.
Following aeration with overseeding introduces resilient cold-hardy grass varieties into bare patches before weeds can take hold in spring.
2. Late-Season Dormant Fertilization
A late-fall fertilizer application high in potassium and slow-release nitrogen strengthens root systems without promoting delicate top growth that frost could kill. Roots continue storing carbohydrates until the ground freezes solid.
3. Final Lawn Mowing & Leaf Removal
Lower your mower blade slightly for the final cut of the season (to about 2 to 2.5 inches). Taller grass matting under heavy winter snow creates an ideal environment for snow mold fungus. Removing fallen leaves prevents smothering light and moisture.
