Every autumn, the same ritual begins again. Leaves fall, rakes come out, and bags fill up. In many gardens, they are still considered waste that should be removed as quickly as possible. However, beneath their apparent ordinariness, dead leaves play an essential role. They protect the soil, nourish microorganisms, and provide shelter to a multitude of species. And if we simply learned to look at them differently? A natural protection for the soil In a forest, no one collects the leaves. They accumulate naturally at the base of trees and form a protective cover. Over time, they decompose and contribute to the formation of humus, a rich organic material that supports plant growth. In the garden, the phenomenon is exactly the same. A reasonable layer of leaves allows the protection of the earth against cold, wind, and heavy rains. It also limits water evaporation and contributes to maintaining more moisture in the soil. This natural cover can also slow the development of certain unwanted plants. It then plays the same role as a commercially purchased mulch, but without transportation, packaging, or additional costs. A refuge for biodiversity Under the dead leaves hides an entire world. Earthworms, pill bugs, insects, mushrooms, and microorganisms participate in their decomposition. By transforming this material, they contribute to enriching and aerating the soil. The piles of leaves can also serve as shelter for hedgehogs and other small animals during the coldest months. Birds sometimes come to search for insects to feed. Systematically removing all leaves therefore amounts to removing part of this habitat, precisely at a time when food and shelters become scarcer. Should we leave all the leaves in place? It is not necessarily a matter of completely abandoning one's garden. Leaves can become slippery on a terrace or a path. On a lawn, a layer that is too thick may also deprive the grass of light and air. Instead of throwing them away, it is possible to move them to places where they will be useful: - at the base of trees and shrubs; - in flower beds; - under a hedge; - in a quiet corner of the garden; - in the compost; - in a fallow vegetable garden. The thickest leaves can be shredded with a lawnmower before being used as mulch. Their decomposition will then be faster. Accepting a garden a little less orderly Our vision of the "beautiful garden" is often associated with perfectly trimmed lawns and completely cleared soil. However, an overly clean space can become a poor space for life. Leaving some leaves on the ground does not mean neglecting one's garden. It allows it to function more naturally. And if, this autumn, we tidied up a little less? Under the leaves, life continues. Sometimes it is enough not to intervene to give it a chance to flourish.
