Leave your leaves help pollinators, save resources

By Blake Jackson

University of Missouri Extension horticulture specialist Manoj Chhetri encourages homeowners to embrace the "Leave the Leaves" movement, highlighting the environmental and ecological benefits. He emphasizes that leaving leaves in your yard provides valuable habitat for pollinators like butterflies, moths, and bumblebees, who in turn become essential food sources for birds.

However, Chhetri acknowledges that a one-size-fits-all approach doesn't work for everyone. He outlines different strategies for managing fallen leaves in various parts of your property:

Vegetable Garden: Shred leaves with a mower or mulcher and till them back into the soil in late fall. This breakdown process adds nutrients while reducing potential pest problems.

Flower Beds: Leaving leaves intact is most beneficial in flower beds. They act as natural shelters for insects, protect the soil, and provide insulation for plants during harsh weather. Avoid shredding leaves in these areas to preserve vital insect habitat.

Grass Yard: Regularly mow or mulch leaves on your lawn to allow them to decompose and return nutrients to the soil. This method, while not directly aiding insects, is preferable to sending yard waste to landfills. Maintain a balance – if leaves cover more than an inch of grass, it's time to shred and redistribute the excess.

Compost Bin: Yard waste, including leaves, is rich in carbon and ideal for composting.

Sharing and Expanding: Consider sharing excess leaves with neighbors who have fewer trees or expand your flower beds to create additional pollinator habitat.

Chhetri acknowledges that mulched leaves may not offer the same visual appeal as a pristine lawn but emphasizes the changing attitudes towards sustainable practices. People are increasingly recognizing the environmental benefits of reducing landfill waste and supporting essential pollinators.

In the sidebar, Chhetri addresses the misconception about black walnut leaves. While the tree produces juglone, a toxin that can hinder plant growth, research shows that the amount remaining in fallen leaves is negligible and poses no threat.

By embracing the "Leave the Leaves" approach, homeowners can contribute to a healthier environment, support vital pollinators, and enrich their own yards.
