Biodynamics is a holistic, ecological, and ethical approach to farming, gardening, food, and nutrition.

Biodynamics is rooted in the work of philosopher and scientist Dr. Rudolf Steiner, whose 1924 lectures to farmers opened a new way to integrate scientific understanding with a recognition of spirit in nature. Biodynamics has continued to develop and evolve since the 1920s through the collaboration of many farmers and researchers. Around the world, biodynamics is alive in thousands of thriving gardens, farms, vineyards, ranches, and orchards. The principles and practices of biodynamics can be applied anywhere food is grown, with thoughtful adaptation to scale, landscape, climate, and culture.
