On Saturday October 12, 2024, Winston Horton, Agroforestry Equity Coordinator at Baton Rouge Green, and Mitchell Provensal, Associate Director of Agroforestry at Baton Roots, co-led a workshop on Fruit Tree Guilds at Baton Roots during the Sow Good Community Resource Festival. Attendees learned about fruit tree guilds, helped to plant trees in the Baton Roots orchard, and took fruit trees home to plant in their homes and neighborhoods.
Baton Roots Community Farm is working with our partners at Baton Rouge Green to expand possibilities for agriculture and forestry in Baton Rouge over the next few years. Learn more about fruit tree guilds and view pictures from the event below.
Definition of a Fruit Tree Guild
A guild is a group of plants that work together to support each other’s growth and health, modeled on natural ecosystems.
A fruit tree guild centers around a primary fruit tree and includes companion plants with complementary functions such as nutrient accumulation, pest control, and pollination. These plants create a self-sustaining ecosystem that mimics nature, reducing the need for human intervention.
Importance of Guilds in Permaculture
Fruit tree guilds play a key role in permaculture by promoting biodiversity, which leads to a healthier, more resilient environment. They improve soil fertility, control pests naturally, and reduce the need for artificial fertilizers or pesticides.
By integrating different plant species, a fruit tree guild provides multiple benefits like habitat for beneficial insects and better water retention, aligning with the sustainable principles of permaculture.
Key Benefits of Implementing a Fruit Tree Guild
Soil Health and Nutrient Cycling
The diverse plants in a guild improve soil structure by adding organic matter through decaying leaves and root systems. Nitrogen fixers enrich the soil with nitrogen, and dynamic accumulators make essential nutrients like potassium available to all plants, leading to a healthier soil ecosystem.
Pest and Disease Management
By planting pest-repellent plants and pollinator attractors, you create a balanced system that reduces the occurrence of pests and diseases naturally. A diverse system also attracts beneficial predators like ladybugs or parasitic wasps that feed on harmful insects, reducing the need for chemical intervention.
Water Retention and Conservation
Ground cover plants and mulchers help retain soil moisture, reducing the need for irrigation. The deep-rooted plants in the guild access water from deeper soil layers, making the entire system more drought-resistant.
Reduced Maintenance and Sustainability
Once a fruit tree guild is established, it requires less maintenance compared to conventional gardens. The natural interactions between the plants reduce weeding, fertilizing, and watering needs, making the system more self-sustaining and aligned with permaculture’s long-term goals.
The Components of a Fruit Tree Guild
The Fruit Tree (Primary Layer)
The central element of the guild is the fruit tree, which provides the primary yield: fruit. The tree benefits from the other plants in the guild, such as those that supply nutrients, attract pollinators, or protect against pests. Choose a fruit tree suited to your local climate and soil conditions—such as citrus, fig, persimmon —depending on what grows best in your region.
Support Plants
Nitrogen Fixers: Nitrogen-fixing plants convert atmospheric nitrogen into a form that plants can use, enriching the soil naturally. This reduces the need for synthetic fertilizers. Examples of nitrogen-fixing plants include clover, peas, beans, lupine, or trees like black locust.
Dynamic Accumulators: These plants have deep roots that bring up nutrients from deeper soil layers, accumulating elements like potassium and phosphorus, which become available to the surrounding plants when they decompose. Examples of dynamic accumulators include comfrey, dandelions, yarrow, or chicory.
Pollinator Attractors: These plants attract bees, butterflies, and other pollinators, which are crucial for fruit set and overall biodiversity. They also contribute to a vibrant, healthy ecosystem by supporting beneficial insects. Examples of pollinator attractors include lavender, borage, marigold, bee balm.
Mulchers/Ground Cover: Ground covers help to protect the soil from erosion, retain moisture, and suppress weeds. They act as living mulch, reducing the need for artificial mulches and conserving water. Examples of mulchers and ground covers include creeping thyme, vetch, strawberries, or low-growing clover.
Pest Repellents: These plants repel pests such as aphids, caterpillars, and rodents, using natural chemicals that deter harmful insects while maintaining balance in the ecosystem. Examples of pest repellents include garlic, chives, onions, tansy, or nasturtiums.
Designing Your Own Fruit Tree Guild
Analyzing Your Site
Site assessment is critical. Look at factors such as soil type (loam, sandy, clay), sun exposure, wind patterns, and water availability. Understand your site’s microclimate, identifying spots with more sun, wind protection, or better drainage.
Selecting Plants for Your Guild
Choose plants based on their ecological function (pollinator, nitrogen-fixer, dynamic accumulator, etc.). Make sure the plants you choose are compatible with the main fruit tree in terms of water, light, and space requirements. Consider plant height and root systems to avoid competition and promote synergy between plants.
Planting and Care
When planting, spacing is essential to ensure that plants don’t compete for resources.
Plant in layers: taller plants should be placed behind the fruit tree, while shorter plants can be closer to the trunk. In the first few years, regular pruning and care may be required to establish the system. Over time, maintenance will decrease as the guild matures and becomes more self-sufficient.
