Biodynamic gardening is a method that goes beyond organic farming, integrating spiritual, ethical, and ecological considerations into the growth of food. Rudolf Steiner, the founder of biodynamics, emphasized the farm as a self-sustaining organism that thrives on the interrelationship between animals, plants, and soil. A core concept within this practice is companion planting, which involves the strategic placement of different plants in close proximity to benefit each other and the garden as a whole.
What is Companion Planting?
Companion planting is the principle of placing plants together that can benefit from each other in various ways. This might be through pest control, pollination, providing nutrients, shade, or support. The objective is to create a harmonious garden that is not only productive but also a balanced ecosystem.
Benefits of Companion Planting
Natural Pest Management
Some plants have natural substances in their roots, flowers, or leaves that can repel pests, which can help protect neighboring plants. For instance, marigolds emit a fragrance that deters nematodes, and their planting beside tomatoes can help prevent these pests.
Improved Pollination
Placing flowering plants near crops can attract pollinators, which is essential for the fruiting of many vegetables and fruits. Bees are more likely to visit your garden if they find a variety of flowering plants, which in turn ensures better pollination for your crops.

Maximization of Space
By carefully considering the spatial needs of plants, gardeners can plant them in such a way that they grow together without competing for light or soil nutrients. Tall plants can provide shade for sun-sensitive shorter plants, while vining plants can be trained up trellises, leaving ground space for other plants.
Nutrient Balance
Certain plants, like beans and peas, fix nitrogen in the soil, which benefits plants that are heavy nitrogen feeders, such as corn. Intercropping these plants can lead to a balance in soil nutrient levels.
Implementing Companion Planting in Your Biodynamic Garden
Selecting Companions
The first step is to plan which plants will go well together. A classic combination is the “Three Sisters” – corn, beans, and squash. The corn provides a structure for the beans to climb, the beans fix nitrogen for the corn and squash, and the squash provides ground cover to control weeds and maintain soil moisture.
Observing Plant Relationships
Observation is key in biodynamic gardening. Pay attention to how plants respond to each other, and adjust your planting strategy accordingly. Do some plants seem to thrive more when close to certain neighbors? This practice is about learning from the garden itself.
Rotation for Soil Health
Rotate crops to ensure soil pathogens specific to one plant do not build up in the soil. This also ensures that the same nutrients are not constantly being drawn from the soil, which can lead to deficiencies.
Creating Diversity in the Biodynamic Garden
Encouraging Beneficial Insects
Planting a variety of flowers among your vegetables can invite beneficial insects such as lacewings and ladybugs that feed on common pests like aphids.
Utilizing Companion Herbs
Herbs are not only for cooking; they can play a big role in companion planting. For example, planting basil near tomatoes is believed to improve their flavor, as well as repel flies and mosquitoes.
Maintaining a Biodynamic Companion Planting Garden
Regular Monitoring and Adjusting
Gardens are dynamic, and what works one season might not work the next. Continually keeping an eye on your plant companions and being ready to rearrange them as needed is important for a biodynamic approach.
Soil Fertility Management
Companion planting reduces the need for artificial fertilizers, but biodynamic gardening also involves preparations made from herbs, minerals, and manure to sustain soil fertility and stimulate plant growth. These are applied according to a biodynamic calendar that is aligned with astral configurations, which Steiner believed influenced plant growth.
Challenges and Considerations in Companion Planting
Space Limitations
Not all gardens have the space to provide ideal companions for every plant. It is important to prioritize based on the most beneficial relationships and the specific needs and limitations of your garden.
Climate and Regional Differences
Companion plants that work well together in one climate or soil type may not necessarily do so in another. Adapt your companion planting choices to the conditions in your garden.
Mistaking Correlation for Causation
Just because two plants grow well together one year doesn’t mean they have a beneficial relationship. Other factors could be at play. Be cautious and continue to observe over multiple seasons before drawing concrete conclusions.
Finishing Thoughts
Biodynamic gardening is a rewarding approach that considers the complex relationships between plants, animals, and celestial forces. Companion planting is at the heart of this holistic practice, not just improving yields but also creating a balanced and vibrant garden ecosystem. By mindfully selecting plant companions and diligently observing their relationships, a biodynamic gardener nurtures not only the crops but also the life of the soil and the garden as an interconnected whole.
