Before raking leaves, know the role they play in natural process for plants, animals

There’s a reason for falling leaves. It might look like the colorful beginning of the end (winter) to many, but like the three other seasons in Ohio, fall is just a necessary transition to the next. If spring is the “growing” season, fall is more than just harvest season; it’s the “replenishing” season.

That means we don’t just take things out of the fields or gardens. What’s left behind is important to native plants and animals, which depend on these cycles for survival.

Before you send the kids out with rakes and demands to see green grass under the newly fallen leaves. And before you start cutting everything down, piling things up, and shipping things away, take the weekend off, and think about the wildlife and the environment we call home.

The sky is not falling

Leaves on the ground serve a number of purposes. If you want to see more lightning bugs, leave more leaves on the ground. The same goes for a number of critters, from frogs to butterflies to amphibians to small mammals and more.

Naturally, leaves on the ground hold in moisture. While they decompose, they increase the fertility of the soil.

I don’t suggest piling dry leaves next to your house, but if you have to move the leaves off of your lawn, consider moving them to a corner of the yard or as mulch onto garden beds. There, they can serve their natural purpose as food, shelter, and returning nutrients to the soil.

Or if you have too many to move or just don’t want to, run over them with a mulching lawnmower. Your grass will thank you.

I had a neighbor who never raked a leaf, but whose yard was still like a carpet of green, in part because he followed that practice.

Stalks and flower heads

Leave flowers and seedheads to overwinter where you can — that’s the natural process. They’ll provide food deep into the winter for birds and other animals, while also providing cover and some shelter from the elements.

If you have to prune back blackberry shrubs and other shrubs, the bundles of branches make great habitat as well. You can cut back the flowers in the early spring before new growth starts, and everyone is happy.

Planting time

While most people associate spring with the planting season, for Mother Nature, while things might grow in the spring, the “planting” really happens in the fall. In fact, some seeds require a period of cool weather followed by the warmth of spring to germinate, in a process called “cold stratification.”

Milkweed, the only host plant for the Monarch butterfly, and many of our favorite trees, including oaks, maples and walnuts, require cold stratification.

Planting in the fall follows this natural process, where fruits and seeds fall to the ground, and are covered by leaves. (The apple doesn’t fall very far from the tree for a couple of reasons.) If you’re planting or moving established plants, doing so now, before the ground freezes, allows them to establish roots without the stress of growing leaves or drought.

They’ll go through winter and hit the warmth of spring, ready to grow.

Planning for a pollinator or native garden

Planting native plants typically requires getting rid of the invasive species first. That’s a step you can take now. A pile of leaves in the area where you want to reestablish native plants could be a great first step. It will help retain water, send nutrients into the soil while blocking light and preventing new growth from starting.

Likewise, purchasing or collecting native seeds now and planting them after a hard frost but before the ground is frozen can help get everything on track.

If you’re interested in collecting seeds or helping out with local native plants in other ways, there are a couple of events coming up in the area.
