Fall leaf cleanup in New Hampshire starts with where the leaves land. A thick blanket over grass needs different treatment from leaves tucked beneath perennial plants. Before you reach for the rake, divide your yard into lawn, garden beds, and a place for excess leaves.
With that simple plan, you can care for the grass while keeping useful organic material on your property.
Start fall leaf cleanup on the lawn
First, check the depth of the leaves on your grass. UNH Extension’s October 24, 2018 guidance explains that heavy leaf cover can smother grass and encourage snow mold. Remove thick accumulations before winter rather than leaving a dense mat until spring.
For lighter cover, that article describes mowing leaves into small pieces that settle between grass blades. However, this approach works best with repeated passes before leaves pile up. If the pieces cannot filter through the grass, rake the excess away.

Leave whole leaves in perennial beds
Meanwhile, UNH’s February 2025 wildlife fact sheet focuses on habitat. It recommends keeping leaves whole because shredding can destroy overwintering insects and their developing stages.
In perennial beds, fallen leaves act as mulch and provide shelter. Standing stems and seedheads also offer habitat for native bees and food for seed-eating birds. Leave those features in place, too.
These recommendations address different goals. Mowing light leaf cover is a lawn-care option. Keeping whole leaves in beds preserves more habitat. To follow the habitat approach, move excess lawn leaves into suitable garden areas without shredding them.
Give extra leaves a destination
Next, decide where any remaining leaves will go. If your lawn produces more leaves than your beds can accommodate, UNH suggests creating a pile to break down naturally. Alternatively, add leaves gradually to compost or offer them to someone who can use them.
Define the garden edge
A clear boundary can also make a natural bed look intentional. For example, the wildlife fact sheet recommends a simple curved edge between the planting area and lawn. Standing seedheads and fallen leaves can remain behind that line.

Start with one section
Finally, choose one stretch of lawn beside a perennial bed for your next cleanup session. Decide where its excess leaves will go before you begin. Then use that small section as your plan for the rest of the yard.
