Stewart has been farming since 2010 at Perennial Roots Farm in Accomac, Virginia, where they make their own biodynamic preparations from animals and herbs grown on their land. He raises cattle, sheep, and hogs, tends a market garden, small orchard, and runs a small CSA while offering internships and workshops throughout the year.
Before farming, Stewart studied Latin, Greek, and political philosophy; during this time he discovered the work of Owen Barfield, who unwittingly prepared the way for understanding Steiner's work later. He first heard about Steiner in Italy while visiting Avignonesi Vineyards in Tuscany where he was impressed by their beautiful attentiveness to spacing their vines. Bees are what got Stewart into farming and an early workshop with Gunther Hauk, founder of the Spikenard Honeybee Sanctuary influenced him significantly. Stewart traveled to the Nature Institute to learn about chromatography concepts with Bruno Follador, and after teaching himself chromatography by sourcing materials described in Ehrenfried Pfeiffer's chromatography writings, has been exploring picture-forming methods actively since 2013. Since 2012, Stewart has been experimenting with biodynamic preparations, and then studied with Hugh Courtney, the founder of the Josephine Porter Institute, for the last seven biodynamic practicums in Woolwine, Virginia and by the end was teaching independent sessions at Hugh's workshops. He has spoken at the Goetheanum in Dornach, Switzerland at the Evolving Science conference, as well as the Pennsylvania Sustainable Agriculture (PASA) Conference, Future Harvest Chesapeake Alliance for Sustainable Agriculture (FHCASA), the Virginia Biological Farming Conference (VABF), the Utah Farm and Food Conference, the national Biodynamic Association (BDA) Conference, a Biodynamic Seminar in Tepetlixpa, México, as well as a regular participant in the Chesapeake Biodynamic Network (CBDN) Conferences. He has given presentations for the Front Range Anthroposophical Cafe (FRAC) among others. In 2024, for the centennial of biodynamics, Stewart edited a collection of some of the best from Hugh Courtney time at JPI's Applied Biodynamics to which he wrote a substantial introduction, published under the title Biodynamics for Beginners (PortalBooks, 2024). He is an independent consultant and helps people transition to biodynamics for farms and gardens worldwide. Stewart's writing has been featured across a wide array of publications including the Biodynamic Journal, Das Goetheanum, Acres, USA, Lilipoh, and more. His farm has been featured in the Washington Post and on NPR. He is the founder and regular contributor to JPI's Substack and oversees the production of biodynamic preparations at the Josephine Porter Institute, made from herbs grown on his farm and manure from his heritage breed cows. He also oversees quality control for the production of JPI's proprietary Pfeiffer™ recipes. In his free time, he studies Hebrew, dabbles in kriya-yoga, and studies esoterica.
