Outdoors with Coggin Heeringa: Recycling Leaves

Sometimes, the most helpful thing we can do for our gardens — and for the life around them — is simply to let nature do the work.

Robert Frost was not a naturalist or a soil scientist. He was a creative writer — a poet.

But he also was a careful observer of the natural world, often using nature and changing seasons to explore deeper human truths.

In his poem "Hardwood Groves," Robert Frost captures something remarkably consistent with how ecosystems actually work: the cycle of death and renewal.

He writes:

"Before the leaves can mount again
To fill the trees with another shade,
They must go down past things coming up,
They must go down into dark decayed.
They must be pierced by flowers and put
Beneath the feet of dancing leaves."

It's a beautiful image — and a grounded one. Fallen leaves don't simply disappear. They're broken down by fungi, bacteria, insects and other soil organisms, releasing nutrients back into the soil.

Those nutrients feed the trees that dropped the leaves in the first place — and the shoots pushing up through the leaf litter each spring.

That moment Frost describes — decaying leaves pierced as new growth rises — is more than poetic. It's the nutrient cycle at work.

Which is why it’s hard not to notice, each fall, how often leaves are raked out of garden beds and hauled away so tulips and daffodils can grow. Not long after, those same beds are treated with store-bought fertilizers to replace what was just removed.

And then come the bird feeders — folks set them out without realizing that that in spring, last year's leaves shelter overwintering insects and other small creatures that birds depend on, especially during nesting season.

Frost didn't speak in scientific terms, but he understood something fundamental: life depends on this quiet, continuous recycling.

We might take the hint.

Sometimes, the most helpful thing we can do for our gardens — and for the life around them — is simply to let nature do the work.
