Leave the Leaves This Fall!

Raking leaves every autumn may seem like a tradition, but did you know that leaving them on the ground can benefit your yard and the environment? 

Luna moths spend the winter as pupae, sheltered in cocoons crafted from fallen leaves and silk. They remain in this stage until late spring, when they emerge as fully developed adult moths.  Photo: M.J. Raupp, University of Maryland

Here’s why you should consider skipping the rake this year:

1. Natural Fertilizer: Fallen leaves break down over time, adding valuable nutrients back into the soil.

2. Wildlife Habitat: Some insects, like monarch butterflies, migrate to avoid the cold temperatures, but there are many insect species that overwinter in various life stages (egg, larva, nymph, pupae, or adult) in Maryland. For example, the great spangled fritillary butterfly overwinters as caterpillar larvae in fallen leaves.  Some bird species also rely on these insects for food. Plant stems, leaves, and other debris can be home to critters that are waiting on warmer days before they emerge this spring. 

3. Water Retention: A layer of leaves acts like mulch, helping the soil retain moisture and reducing the need for extra watering. It also helps prevent soil erosion during rainy months.

4. Reduce Waste: Bagging leaves and sending them to landfills contributes to unnecessary waste. Instead, you can let leaves decompose naturally.

5. Save Time and Energy: Skipping the rake means more time to enjoy fall activities like hiking, pumpkin carving, or cozying up with a warm drink!

During the winter months, plant stems, leaves, and other garden debris provide shelter for many beneficial insects that are waiting for warmer weather to emerge in the spring. Try to hold off on clearing away plant materials for as long as possible.  Photo: M.E. Potter, University of Maryland Extension
