Leaf It Alone?

Every autumn, the trees put on a spectacular show, carpeting lawns, gardens, and sidewalks with gold, orange, and brown. Then comes the question: Should we rake them up or let them lie? Increasingly, ecologists and gardening experts are making the case for letting leaves stay where they fall.

Did you know The National Wildlife Federation even designates October as Leave the Leaves month, encouraging property owners to rethink the traditional fall cleanup? Although in Springdale, that would be more appropriate in November. Thus, this is going in The Springdale Sun’s last issue in October.

Fallen leaves are more than yard waste. They provide shelter for overwintering butterflies, moths, fireflies, and other beneficial insects. Many small creatures depend on leaf litter to survive the winter, and those creatures, in turn, provide food for birds and other wildlife. Leaves also break down into organic matter, returning nutrients to the soil, improving its structure, and helping it retain moisture. In gardens and around trees and shrubs, they can serve as a natural mulch, suppressing weeds and protecting plant roots from temperature extremes.

But that doesn't mean we should abandon the rake altogether. A thick, wet blanket of leaves can smother grass, and leaves that cover sidewalks, driveways, or storm drains can create slippery conditions or obstruct drainage. Diseased leaves may also need to be removed to reduce the spread of certain plant diseases. In these situations, a little cleanup makes sense.

So what's the best approach? Think selectively, rather than automatically raking everything away. Leave leaves in garden beds, beneath shrubs, around trees, and in less-used corners of your yard. If leaves pile up on the lawn, consider mowing over them to chop them into smaller pieces that can decompose more quickly and nourish the grass. Keep paths, drains, and other necessary areas clear.

If you do collect leaves, consider composting them rather than sending them to the landfill. Shredded leaves make excellent additions to compost and can become valuable soil amendments.

A tidy yard doesn't have to be a lifeless one. By allowing nature to do some of the work, we can reduce yard maintenance, enrich our soil, and provide essential habitat for wildlife. This autumn, perhaps the best question isn't whether to rake, but where to leave the leaves.
