Fall leaves a gillion little gifts on the ground. Before you haul it away, consider letting some of it do what it does best—feed the place you live and leave the leaves.

We are no strangers to leaf drop in the upper left coast, it can be the star of our entry into fall and also an annoyance for some. We think leaves are pretty special and we’d like you to know more about how leaving them, can create less of a headache for you and actually add to your garden.

Top 4 Reasons to Leave the Leaves this Fall:

1. Leaving the leaves is cost-effective

Free mulch, right where you need it. You don’t need to spend extra time and money raking your leaves, collecting them, and moving them over to your compost bin. Leaves protect and soften the soil, deter some weeds, and slowly turn into food for your plants. Forests have been providing their soil with free mulch for thousands of years. It’s time we take a hint Not to mention, it’s free! We love free.

2. Wildlife loves it when you leave the leaves

Think about all the insects, birds, salamanders, earthworms, and other small animals preparing their home for the upcoming winter. Leaves are an important tool used by these critters to keep warm and survive the winter.

Tiny wildlife need you to leave the leaves (and so do baby birds). A loose leaf layer shelters insects, spiders, and worms—the spring protein snacks for nestlings you’ll rarely see, but they depend on them. While they may not be your favorite, baby birds thrive on them by the thousands.

3. Leaving the leaves improves soil health

Your soil could use coverage during the cold months. Bare soil gets pounded by rain and footsteps, sealing the surface and squeezing out the air pockets that roots and soil life need. A light blanket of leaves cushions raindrops, spreads foot pressure, and helps maintain that crumbly, living structure.

Instead of buying extra mulch for winter, use the leaves you already have on-site! They not only suppress weeds but also break down over the coming seasons, fertilizing your soil naturally!

4. It’s less fuss and lower maintenance to leave the leaves

Reduce your fall workload while doing the best thing for your soil and local pollinators. Instead of bagging your leaves, rake or blow off your paths and driveway. Then tuck those leaves into beds or under shrubs. Done.

You’ll spend less time chasing bags around the yard and wrestling your leaf pile into your compost bin. Plus you get to enjoy watching the leaves fall instead of stressing about the clean-up.

How to “leave the leaves” without the mess:

Keep paths, drains, and lawns clear for safety—slide those leaves into planting beds.

Aim for a loose, airy layer (about 1–3 inches). If you really want it to break down quickly, you can always shred them with a machete or a mower. I personally don’t recommend this, but I understand the desire.

If you are hesitant to leave them all, make a corner leaf pile for extras; raid it later as free mulch. This is called leaf mold, and we will discuss it more in a future blog post.

How to leave the leaves while protecting your plants

There are a few caveats to the practice of leaving your leaves that we need to talk about.

First, if your leaves are showing the presence of disease, we do recommend removing and composting them.

Next, the rules are different for fruit trees and roses. To take care of these plants, rake out all the leaves from, especially from pear trees, and send to Clean Green. Do this even if no rust is visible. Then mulch your fruit trees and roses with woodchip mulch or other organic materials.

A note for the PNW: With our wet winters, leaf layers usually settle and break down on their own. If you’re nervous, start by leaving some and see how it looks come spring.

Bottom line: You don’t have to keep every leaf. Just keep enough to cover soil, prevent compaction, and share a little warmth with the small neighbors who live here, too.

Consider adopting this habit and asking your maintenance team to do the same. We are advocates for this practice and are happy to talk more about it if you have hesitations!
