Autumn leaves are habitat, not simply yard waste. Discover a practical middle ground between tidy pathways and a living landscape. Ontario's changing seasons and diverse landscapes make even a small backyard a fascinating place to observe nature.
A layer with a purpose
Fallen leaves shelter overwintering insects, help protect soil from temperature swings, and gradually return organic material to the ground. Many moths and other invertebrates spend part of their lives in leaf litter; birds may forage among them.
Where to leave them
Keep a layer under shrubs, in perennial beds and beneath trees. Move leaves off walkways, drains and heavily used lawn areas. Avoid deep, wet mats over turf if maintaining grass matters to you.
How to manage excess leaves
Rake leaves into garden beds or a loose leaf pile in a sheltered corner. Shredded leaves can be used as mulch, but leave some intact for wildlife. Avoid piling against tree trunks or building foundations.
What about spring cleanup?
Delay aggressive cleanup while the soil is cold and overwintering insects may still be present. There is no universal calendar date: local weather and habitat conditions matter.
A balanced Ontario yard
A useful compromise is clear paths and play spaces alongside leaf-rich garden beds, native plants and an undisturbed corner. You do not need to abandon lawn care to support biodiversity.
