You don't need to be an avid gardener to reap the benefits of growing your own produce, says garden expert Trevor Cochrane.
He said sustainable gardening could be as simple as placing tomato and blueberry plants among existing plants or having potted herbs.
For more of a challenge, householders could try a chook pen, a small fish farm, and a fruit and - if there's room - a vegetable garden.
To inspire gardeners, he has set up a 600sqm demonstration food production garden for the IGA Perth Royal Show that features aquaponic tanks, a chicken house, worm farms, vegie beds, an urban orchard, a recycle green waste area, herbs and a plant propagation area.
Cochrane said the display garden's 32 fruit trees could produce up to 1600kg of fresh fruit a year.
He estimated his sustainable backyard garden in Kalamunda cut about $160 off his family's weekly food bill as it produced an endless supply of fish, eggs, fruit, herbs and vegetables.
Aside from the economic benefits, he said more people were adopting sustainable gardening as a way of life because of the nutritional benefits of eating fresh food that tasted better.
"Sustainable gardening is setting up an environment that provides you with the highest-quality food along with an environment that you will really enjoy and want to sit and relax in," Cochrane said.
"Knowing where your food has come from and the reward of growing it yourself is awesome."
