In nature, every available space is filled with life—trees stretching towards sunlight, vines climbing upwards, and roots delving deep underground. Inspired by this natural abundance, the seven-layer food forest principle teaches us how to stack plants vertically, maximising productivity and creating vibrant, resilient ecosystems.

At Carinya Parc, we’ve embraced the seven-layer concept to transform our landscape, growing a diverse range of nutritious food while enhancing biodiversity and soil health. Here’s our practical guide to understanding and implementing these seven layers in your own garden or farm.

What is a Seven-Layer Food Forest?

A seven-layer food forest mimics natural forest structures, creating multiple vertical layers of plants that interact beneficially. Instead of traditional gardens with rows of plants at ground level, food forests grow upward, making better use of sunlight, nutrients, and space.

This design encourages biodiversity, reduces pests, conserves water, and builds soil health naturally—no synthetic chemicals needed.

The Seven Layers Explained

1. Canopy Layer

The tallest trees form the canopy, providing shade, wind protection, and habitat for birds and wildlife. In Australia, this layer often includes:

• Macadamia
• Pecan
• Avocado
• Spotted Gum (timber)

Canopy trees moderate the microclimate, protect the soil, and yield valuable nuts, fruits, or timber.

2. Sub-Canopy Layer

Beneath the canopy, medium-sized trees produce fruit and nuts and provide additional shade and habitat. Ideal sub-canopy plants include:

• Apples and Pears
• Citrus (oranges, lemons)
• Figs
• Carob (nitrogen-fixer)

These trees occupy the space below the tallest canopy trees, further optimising sunlight use.

3. Shrub Layer

Shrubs deliver continuous harvests of berries, herbs, and flowers, filling gaps between larger plants and attracting pollinators. Popular shrubs for this layer:

• Blueberries and Raspberries
• Rosemary and Lavender
• Gooseberries and Currants
• Native herbs (Lemon Myrtle)

Shrubs protect the soil, control weeds, and produce abundant harvests.

4. Herbaceous Layer

This layer includes annuals, perennials, vegetables, and medicinal herbs that grow close to the ground. Plants in this layer:

• Asparagus and Rhubarb
• Basil, Oregano, Sage
• Jerusalem Artichokes
• Comfrey (soil-improver)

The herbaceous layer is highly productive and quick to establish, providing regular food and medicine.

5. Ground Cover Layer

Low-growing plants protect soil moisture, suppress weeds, and even offer delicious harvests:

• Strawberries
• Thyme and Mint
• Clover (nitrogen-fixer)
• Native violets

Ground covers prevent erosion, maintain soil health, and attract beneficial insects.

6. Climbing Layer (Vertical)

Vertical space is maximised by vines that climb trees, fences, and trellises. Examples include:

• Passionfruit
• Kiwi
• Grapes
• Climbing beans and peas

This layer produces additional food without taking up extra ground space.

7. Root Layer (Underground)

The hidden underground layer produces root vegetables and tubers, while also improving soil structure and aeration:

• Garlic, Onions, and Shallots
• Daikon radishes (soil aeration)
• Native yams and edible tubers
• Yacon and Jerusalem Artichokes

The root layer enhances soil fertility and provides seasonal storage crops.

Designing Your Seven-Layer Food Forest

Observe Your Site

Identify sunlight patterns, soil conditions, wind direction, and rainfall. Understanding these factors guides plant selection and placement.

Select Complementary Plants

Choose plants that help each other grow—nitrogen-fixing plants (like wattles and legumes) improve soil nutrients, aromatic herbs deter pests, and flowering plants attract pollinators.

Plan for Succession

Start with fast-growing plants to create shade and improve soil, followed by slower-growing fruit and nut trees. Over time, the system evolves, becoming more productive and resilient.

Benefits We've Seen at Carinya Parc

Implementing the seven-layer system has already shown clear benefits:

• Higher Productivity: Multiple crops from one space.
• Improved Soil: Healthier, richer soil with fewer inputs.
• Water Conservation: Reduced irrigation needs through improved soil moisture.
• Pest Reduction: Greater biodiversity naturally controls pests.
• Year-Round Harvests: Continuous yields from different layers throughout the seasons.

Getting Started: Practical Tips

• Begin Small: Start with one small area, build confidence, then expand gradually.
• Mulch Heavily: Protect soil moisture and suppress weeds with generous mulch.
• Choose Robust Species: Start with hardy, easy-to-grow plants suitable to your climate.
• Observe and Adapt: Continually learn from your plants, adjusting your approach as needed.

Conclusion: Vertical Gardening, Maximum Abundance

The seven-layer food forest isn’t just a clever gardening method—it’s a way of thinking about the natural world. By understanding and mimicking nature’s patterns, we create landscapes that produce abundant, nutritious food while regenerating the environment.

At Carinya Parc, each new season deepens our appreciation for these interconnected layers. Our food forest reminds us that we can produce food sustainably, build healthy ecosystems, and enhance our community's resilience at the same time.

In stacking layers vertically, we grow far more than just plants—we cultivate hope, resilience, and abundance.

"A seven-layer food forest isn’t just gardening vertically; it’s a way to create abundance, biodiversity, and resilience within your landscape."
