Learn about vertical, temporal, and functional stacking to maximize productivity and harmony in your garden. Discover the power of stacking in permaculture.
Permaculture, a design philosophy aimed at creating sustainable and self-sufficient agricultural systems, uses the concept of stacking to maximize productivity and efficiency.
Stacking involves integrating multiple elements in both space and time, creating a harmonious and productive ecosystem.
This practice mimics natural ecosystems, where diverse species coexist and support each other, resulting in a resilient and thriving environment.
Permaculture employs three primary types of stacking: vertical, temporal, and functional. Each type leverages different aspects of the ecosystem to enhance productivity and sustainability.
Vertical Stacking
Vertical stacking utilizes the vertical space in a garden or farm to grow multiple layers of plants, akin to a natural forest structure. This method allows for a dense and diverse planting scheme.
Canopy Layer: Tall trees, such as apple or oak, form the topmost layer, providing shade and support.
Understory Layer: Smaller trees or large shrubs, like hazelnut bushes, thrive beneath the canopy.
Shrub Layer: Plants like blueberries or currants grow in partial shade, benefiting from the taller layers above.
Herbaceous Layer: Herbs and vegetables, such as mint and lettuce, occupy this layer, making use of the space below shrubs.
Ground Cover Layer: Low-growing plants like clover cover the soil, preventing erosion and suppressing weeds.
Rhizosphere (Root Layer): Root crops like carrots and potatoes grow underground, utilizing the soil layer.
Vine Layer: Climbing plants, such as beans or grapes, use taller plants or structures for support.
By stacking these layers, a permaculture garden maximizes the use of vertical space, leading to a more productive and biodiverse system.

Temporal Stacking
Temporal stacking involves planning the succession of crops or activities over time to ensure continuous productivity and resource use.
Seasonal Planting: Different crops are planted and harvested throughout the year, such as planting leafy greens in spring, tomatoes in summer, and root vegetables in fall. An exemplary case is Masanobu Fukuoka’s rice and barley rotation, where rice is grown during the wet season, and barley (or rye) during the dry season. This method leverages natural seasonal cycles to keep the land productive year-round while maintaining soil health.
Succession Planting: Sequentially planting different crops in the same space throughout the growing season, like following early-harvest lettuce with late-season beans, ensures continuous soil use and harvest.
Intercropping: Growing multiple crops that mature at different times in the same space. For instance, planting quick-growing radishes alongside slower-growing carrots allows for a staggered harvest.
This approach keeps the soil covered and productive year-round, reducing erosion and maintaining soil fertility.
Functional Stacking
Functional stacking integrates multiple functions within a single element to increase efficiency and reduce waste.
Polycultures: Planting a variety of species together, such as the Three Sisters (corn, beans, and squash), which support each other by providing structure, fixing nitrogen, and suppressing weeds.
Integrated Animal Systems: Using animals for multiple purposes. For example, chickens provide pest control by eating insects, produce manure that enriches the soil, and offer eggs and meat as food sources. Ducks can be integrated into rice paddies to eat pests and weeds, aerate the water with their movement, and add fertility through their droppings.
Multifunctional Structures: Designing elements that serve several purposes. For instance, a greenhouse can provide warmth for plants, serve as a living space for small animals like rabbits or chickens, and collect rainwater for irrigation. Another example is a pond that supports fish farming, provides water for irrigation, and creates a microclimate that benefits surrounding plants.
By stacking functions, permaculture systems become more efficient and resilient, making the most of available resources.
Benefits of Stacking
Stacking in permaculture offers numerous benefits:
Maximized Space: Efficient use of vertical and horizontal space increases productivity without expanding the footprint.
Increased Biodiversity: Diverse species enhance ecosystem resilience and stability, reducing the risk of pests and diseases.
Improved Soil Health: Diverse plant root systems and organic matter contribute to richer, more fertile soil.
Resource Efficiency: Utilizing every part of the system reduces waste and improves energy use, creating a more sustainable environment.
Stacking is a fundamental principle in permaculture that leverages the natural synergies between different elements to create a highly productive, sustainable, and efficient system. This approach not only enhances productivity but also contributes to the overall health and sustainability of the environment.
