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

As the global community switches to regenerative agricultural practices to secure our planetary health, 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 transition from a "chemically-dependent" garden to a self-sustaining ecosystem.

You'll learn the secrets of Mycelium—the vast underground networks of fungal hyphae that can extend for miles. These hairlike "arms" act as a living superhighway, delivering nutrients and water directly to your roses while shielding 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 rose's new best friend.


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


This event is FREE and open to the public.  Registration and more details coming this summer, so mark your calendar!
