Nature’s Network: Harnessing the Soil Food Web ~ A New Paradigm for Rose Culture ~ (20 Sep 2026)

Sun, 20 Sep 2026 18:00:00 GMT

Nature never uses a bag of fertilizer—so why do we?

As the global community embraces regenerative agricultural practices to help safeguard the health of our planet, the Potomac Rose Society is thrilled to welcome Leslie Lewis, Soil Food Web School board member, and founder of Living Systems Soil, LLC , for an exclusive deep dive into the microscopic world beneath our feet.

During this session, you will discover how to move beyond conventional fertilizer-based gardening toward a more self-sustaining ecosystem.

You'll also discover the remarkable world of mycelium—the vast underground networks of fungal hyphae that can extend for miles. These intricate, living networks act as nature's underground superhighway, delivering nutrients and water to plant roots while helping to protect them from disease and pests.

That's right! If you feed your soil the right way, you may never have to feed your roses again!

We will also cover:

How to brew your own Actively Aerated Compost Tea (AACT) at home—a potent biological "shield" for your plants.
Which common gardening practices are hurting your soil's microbiome?
The specific "superfoods" that turn soil fungi into your roses' new best friends.

As a certified consultant and Board Member of the Soil Food Web School, Leslie is at the forefront of the movement to preserve the legacy of the late Dr. Elaine Ingham. She will share transformative insights on how living microorganisms—not chemicals—are the vigilant guardians of your garden’s health.

"The living microorganisms in the soil are the overlooked foundation of planetary health." — Leslie Lewis
