Leaf Mulch: A Natural Solution for Your Garden
As autumn arrives, many of us reach for rakes and bags, preparing to haul fallen leaves to the curb. But those crisp, colourful leaves piling up in your yard? They’re more than just yard waste—they’re a valuable resource for your garden.
Leaf mulch is an easy and sustainable way to improve your soil and support plant health through the colder months. When applied to garden beds, leaves form a natural mulch layer that helps insulate the soil, moderates winter temperatures, and retains moisture. As the leaves break down, they add organic matter to the soil and release valuable nutrients.
There are two main ways to apply leaf mulch:
Whole leaves: Spread a light layer directly over your garden beds. This method allows the mulch to last longer, but be sure not to pile them too thickly, as this can create a mat that blocks water and air.
Shredded leaves: For quicker decomposition, shred the leaves before applying. A bagging lawn mower is perfect for collecting and chopping dry leaves, or you can use a mulching mower and simply rake the shredded material into your beds.
Keep in mind that not all leaves decompose at the same rate. Leaves from trees like magnolia and sycamore are slow to break down due to their tough, leathery texture and higher lignin content. Evergreen leaves such as holly and laurel are also slow to decompose because of their waxy coating.
By rethinking your fall cleanup routine, you can give your garden a nutrient-rich boost and reduce waste—all with the leaves already in your yard.
