Biodynamic Gardening
Introduction to Biodynamic Gardening
Biodynamic gardening is a holistic, spiritual, and deeply ecological approach to growing plants. Originally developed by Austrian philosopher Rudolf Steiner, biodynamics integrates organic farming practices with cosmic and lunar influences, spiritual science, and a deep understanding of nature’s rhythms.
For gardeners across the USA, biodynamic gardening offers more than just sustainable techniques—it’s a pathway to reconnect with the earth, soil, and seasons. This comprehensive guide explores how American gardeners can use Biodynamic Gardening to grow healthier plants, revitalize soil, and become stewards of a living ecosystem.
Origins and Principles of Biodynamic Gardening
Rudolf Steiner and the Birth of Biodynamics
In 1924, Rudolf Steiner responded to farmers’ concerns about soil degradation and declining crop quality by presenting a series of lectures known as the Agriculture Course. These teachings formed the basis of biodynamic agriculture, emphasizing the spiritual interconnectedness of soil, plants, animals, and the cosmos.
Gardening as a Living Organism
In biodynamic thinking, your garden isn’t just a collection of plants—it’s a self-sustaining living organism. Every element, from compost to pollinators to planetary movement, plays a vital role in the garden’s health.
Cosmic Rhythms and Lunar Gardening
A major tenet of biodynamic gardening is lunar and planetary alignment. Biodynamic gardeners use an astronomical calendar to plan planting, pruning, harvesting, and composting based on:
- Moon phases (ascending/descending)
- Constellation alignments
- Planetary aspects
These cycles are believed to influence root growth, flowering, and even pest resistance.
How Biodynamic Gardening Differs from Organic Gardening
Similar Roots, Deeper Practices
While biodynamic and organic gardening share practices like avoiding synthetic pesticides and building soil health, biodynamics goes further. It:
- Involves spiritual awareness
- Uses homeopathic preparations
- Emphasizes cosmic rhythms
Biodynamic Certification vs. Organic Certification
In the USA:
- USDA Organic focuses on input restrictions.
- Demeter USA certifies biodynamic farms based on holistic criteria including biodiversity, closed-loop systems, and use of specific BD preparations.
Starting Your Biodynamic Gardening: A Step-by-Step Guide
Step 1 – Observe Your Garden as a Whole
Before making changes, spend time observing your garden:
- Where is the sun strongest?
- What microclimates exist?
- Are certain plants or insects thriving?
Step 2 – Test and Revive Your Soil
Healthy soil is the cornerstone of any biodynamic garden. Use a soil test to check:
- pH levels
- Nutrient deficiencies
- Organic matter content
Incorporate cover crops, green manures, and biodynamic compost to build rich, living soil.
Step 3 – Use the Biodynamic Gardening Calendar
Follow the biodynamic planting calendar to align tasks with cosmic forces. For example:
- Root vegetables (e.g., carrots, beets) are planted during descending moons.
- Leafy greens are best planted during leaf days under water signs.
These calendars are available through the Biodynamic Association and customized for USA time zones.
Understanding Biodynamic Gardening Preparations (BD 500–508)
BD 500 – Horn Manure
Cow manure is packed into a cow horn and buried over winter. After months of fermentation, the preparation becomes rich with microbial life and is sprayed to enhance soil structure and vitality.
BD 501 – Horn Silica
Ground quartz is buried in a cow horn over summer. When sprayed in the morning, BD 501 enhances photosynthesis and light absorption in plants.
Compost Preparations (BD 502–507)
Each of these uses herbs to bring balance:
- Yarrow (502): Helps plants utilize trace minerals.
- Chamomile (503): Stabilizes nitrogen.
- Nettle (504): Activates soil life.
- Oak Bark (505): Provides calcium and helps against disease.
- Dandelion (506): Stimulates silica and potassium.
- Valerian (507): Promotes phosphorus flow.
BD 508 – Horsetail Tea
Used to control fungal diseases such as mildew or rust, especially useful in humid climates like the Southeastern USA.
Biodynamic Gardening Composting: The Heart of the Garden
How It Works
Biodynamic composting differs from regular composting by integrating specific herbal preparations into the pile to guide fermentation and nutrient balance.
Creating Your Biodynamic Gardening Compost
Layer:
- Kitchen scraps (green)
- Dried leaves (brown)
- Soil or manure
- BD compost preps (502–507)
Cover and turn regularly to promote aerobic decomposition.
Tips for Composting in Different USA Climates
- Northern states: Use insulated bins or indoor worm bins during winter.
- Southwest: Add more browns to balance high moisture loss.
- Midwest: Turn frequently in humid summers to prevent anaerobic buildup.
Biodynamic Gardening by the Moon and Stars
Planting with the Moon Phases
The ascending moon favors plant growth above ground; the descending moon is ideal for root development.
Understanding Zodiac Constellations
Each constellation correlates to a plant element:
- Earth signs (Taurus, Virgo, Capricorn): Roots
- Water signs (Cancer, Scorpio, Pisces): Leaves
- Air signs (Gemini, Libra, Aquarius): Flowers
- Fire signs (Aries, Leo, Sagittarius): Fruits
Using Lunar Tools in the USA
Several biodynamic apps and North American lunar gardening guides help plan regional planting based on accurate ephemeris data.
Growing Biodynamic Crops
Best Plants to Start With
- Heirloom vegetables: tomatoes, kale, beans
- Medicinal herbs: lavender, echinacea, calendula
- Aromatic herbs: basil, thyme, rosemary
- Perennials: fruit trees, berry bushes
Biodynamic Gardening Seed Sources in the USA
- Baker Creek Heirloom Seeds
- High Mowing Organic Seeds
- J.L. Hudson Seedsman
Choose open-pollinated, non-GMO, and Demeter-certified seeds where possible.
Pest and Disease Management Without Chemicals
Build Plant Immunity Naturally
Healthy, balanced soil leads to resilient plants. Regular BD sprays strengthen their immune system.
Companion Planting
Mixing crops like:
- Marigolds with tomatoes (repel nematodes)
- Nasturtiums with squash (trap aphids)
- Basil with peppers (repels whiteflies)
Animal Allies and Insect Diversity
Encourage pollinators and predatory insects like:
- Bees
- Ladybugs
- Lacewings
- Birds and bats
Urban Biodynamic Gardening in Small Spaces
Raised Beds and Container Gardening
Even in a city apartment, you can grow biodynamically:
- Use compost-based soil
- Stick to lunar planting cycles
- Make mini composts or worm bins
Community Gardens and Biodynamic Gardening Collectives
Cities like Portland, Chicago, and Brooklyn have community gardens using biodynamic methods. Check local cooperative extensions for leads.
Essential Tools and Techniques
Biodynamic Composting Tools
- Compost thermometer
- Aerator fork
- Cow horns for BD 500
- Barrel composting setup
Spraying Biodynamic Gardening Preparations
These are typically applied using a stirring method and sprayed at dusk or dawn to align with cosmic forces. Use:
Copper spray nozzles (to avoid chemical reactions)
Vortex stirrers
Backpack sprayers
Biodynamic Gardening in Different U.S. Regions
Northeast
- Rich in biodiversity, cold winters.
- Build deep beds and compost heavily.
Southeast
- High humidity and fungal pressure.
- Use BD 508 (horsetail) regularly.
H3: Midwest
- Heavy clay soil—use green manure and mulching techniques.
Southwest
- Drought-prone. Prioritize mulching, shade, and water retention.
Pacific Northwest
- Cool and wet—ideal for herbs, fruit trees, and soil fungi.

Who Should Get Certified?
While home gardeners don’t need certification, market gardeners, CSA owners, and herb farms may benefit.
Common Myths About Biodynamic Gardening
It’s Just Woo-Woo Gardening
Many skeptics dismiss biodynamic gardening as mystical nonsense. However, research and success stories from regenerative farms in the USA prove the method improves soil health and crop resilience.
It’s Too Complicated
While it can seem overwhelming, beginners can start small—by using compost preparations or timing their planting by the moon.

- Books: Biodynamic Gardening by Maria Thun
- Tools: Vortex stirrers, copper sprayers, lunar planting apps
Frequently Asked Questions (FAQs)
Can I mix biodynamic with organic or permaculture methods?
Yes! Many American gardeners successfully blend biodynamics with permaculture design and organic principles.
Are the preparations expensive?
No—many are DIY. However, Demeter-approved preps can also be purchased online if needed.
Do I have to use the moon calendar strictly?
It’s recommended but not mandatory. Start with one element, like planting by moon phase, and grow from there.
