Creating a Sustainable Ornamental Garden: Principles of Per-maculture

Do you value sustainable practices in the garden? Would you like to learn the philosophy that the experts use to garden sustainably?

The twelve principles of permaculture —a design philosophy pioneered by Bill Mollison and David Holmgren provide us with the framework to help us design, construct and maintain landscapes of all sizes that benefit the environment without costing the earth.

Permaculture is usually associated with gardens focusing on edible crops, but the philosophy applies just as well to ornamental gardens – even indoor gardens and green walls! Feel free to apply any and all of these principles as they apply in your own garden.

Observe and Interact

The first step in creating a self-sustaining garden is to observe the site meticulously. Understanding local conditions such as sunlight, wind patterns, soil types, and existing vegetation allows for informed decisions that work with nature. What pests and diseases are present in the neighbourhood?

How does the sunlight change throughout the seasons?

Catch and Store Energy

Incorporate features like rainwater tanks, swales, compost bays, and solar lighting into your landscape. These elements capture and store energy, reducing reliance on external resources and enhancing the garden’s efficiency and self-sufficiency.

Obtain a Yield

While ornamental gardens focus on visual appeal, they can still provide practical yields. Integrating edible plants, herbs, or native bush foods adds value and biodiversity. Yield goes beyond food as well; you can frame all plant functions as a yield, from providing aesthetic beauty to shade to sit under and have a cup of tea.

Apply Self-Regulation and Accept Feedback

Regularly assess your garden’s health and performance. Adaptive management involves using environmental feedback—such as plant vitality and water usage—to refine maintenance practices, ensuring the garden’s long-term success.

Don’t get upset when something doesn’t go to plan – instead, learn from your mistakes. Seek the advice of experienced horticulturists or gardeners, and be willing to listen.

Use and Value Renewable Resources and Services

Choose renewable materials like recycled timber, locally sourced stone, and organic mulch for your landscape construction. The closer to your home you can source resources, the better – see what you have lying around before getting in your car to head to the big green shed. That way, your garden will be both sustainable and uniquely decorated.

Produce No Waste

Adopt a zero-waste mindset by composting garden waste, using biodegradable materials, and designing for minimal waste production. Plastic bottles can be re-used for mixing liquid fertilisers and horticultural oils, cardboard can be composted, and meat scraps can be broken down through bokashi composting or soldier fly larvae.

Design From Patterns to Details

Identify larger landscape patterns such as water flow, wind direction, and animal pathways before delving into specifics like plant selection and garden layout. Consider successful ways that other people have solved the challenges you’re facing in the garden.

Don’t try to re-invent the wheel. Design your garden around the natural systems and approaches already in place, rather than trying to bend nature to your will.

Integrate Rather Than Segregate

Nature doesn’t respect our borders and definitions, so follow her lead. Put a bench seat inside the garden bed, rather than separate from it.

Create diverse plant communities by integrating various species that each serve a purpose, such as attracting pollinators, providing shade, or improving soil health. Diversity strengthens the ecosystem and reduces vulnerability to pests and diseases.

Use Small and Slow Solutions

Start with manageable projects that can be gradually expanded. This way, you prioritise learning and adaptation rather than quick results, reducing the risk of projects getting out of hand and overwhelming maintenance demands.

Use and Value Diversity

A diverse garden is more resilient to pests, diseases, and climatic changes. Incorporate a mix of endemic, native and exotic plants from a variety of species, genera, families and orders to create a robust and visually appealing landscape. Diversity ensures that if one species fails, others can fill its ecological niche.

Use Edges and Value the Marginal

Edges—such as the borders between lawns and flowerbeds or paths and planting areas—are often underutilised. Maximising these spaces for additional planting creates microhabitats and increases biodiversity, adding layers of interest and functionality to the garden.

Creatively Use and Respond to Change

Landscapes are dynamic systems subject to change. Whether due to climate variability, growth cycles, or evolving personal preferences, embrace change as an opportunity for creative enhancement and garden evolution.

Daniel’s Wrap

The principles of permaculture offer a comprehensive framework for creating sustainable ornamental gardens in Australia and the rest of the world. By aligning with these principles, we can cultivate beautiful, functional, and sustainable landscapes that enrich the environment and captivate the senses.
