This year’s event features Mary Robson of Port Townsend, Washington, as the keynote speaker. Robson will be telling the story of how roots work with a little help from their friends, soil fungi and bacteria. Robson is a master storyteller when it comes to explaining how things work in the garden. She combines her years as a WSU extension horticulture specialist, author, writer and gardener to narrate the story behind the science and the beauty of the microorganisms in the soil’s rhizosphere.
