We are on Dharawal Country, the unceded ancestral lands of the Dharawal, Wadi Wadi, and Yuin people. We acknowledge and pay our respects to Elders past, present, and emerging, and to Country itself. Aboriginal people successfully managed this land for 10s of thousands of years. They achieved this by passing down their accumulated knowledge and applying processes such as the strategic use of fire. They managed food sources, both plant and animal were not only sustainable but abundant, convenient, and predictable. And they protected water sources that are diminishing today from longwall mining. We strive to ensure traditional knowledge is incorporated into the management of this land.
Our Food Forest Roots
In 1993 we began in Mt Kembla with an acre of Kikuyu lawn with mature trees. It was a lovely parkland style of remnant orchard and ornamental trees. Mt Kembla was an arty village community close to the University city of Wollongong. But it also had a dark history. It is the first place that Koalas discovered white man. And it is the site of Australia’s first industrial disaster and home to surviving widows and families who were never trusted with their compensation money.
But our ‘dry’ rainforest has kept its beauty. And within it, we have built a rich permaculture lifestyle. In the beginning, our children were babes. It took 6 hours to mow the acre of Kikuyu. This is partly why we were able to purchase the property. The upkeep of a traditional house and yard was exhausting. There were extensive tracts of woody weeds including lantana, honeysuckle, oleander, and tobacco plants. And we didn’t know how to catch a chicken, graft a seedling, manage snails or pickle a chili.
Now we share our abundant produce, delight in the wildlife, share know-how and support ethical social enterprises. Because Permaculture is not peasant living. It is a lifestyle. Although Permaculture is much more than a food forest, the food forest sustains our interest and wonder.
The resilience and bounty of the food forest offers many a better future.
Admire, Analyse and Engage
The design process is a series of plans rather than a static end goal. The process is rooted in healthy ethics and working toward to clear vision. We have a vision of what success looks like and each plan works towards meeting that vision. We adapt the strategies and techniques. The whole process evolves in response to feedback from the living system.
Different Microclimates support rare species.
Tropical plants such as Jackfruit grow around the bend from temperate fruits like strawberries.
We were the first in our bio-region, [and possibly the most southern reaches of Australia] to grow Jackfruit, Peruvian custard apple, Lychee, Longan, Sapodilla, and Jabuticaba. We didn’t realise how many firsts we had achieved at the time. We were curious and adventurous. Our grandparents had taught us both to marvel, respect and value nature.
A key part of our journey has been the wisdom of our elders. And we continue to listen to advice. In our travels we have kept a passion for archeology, and respect for indigenous people and plants. We are always building our knowledge of ecosystems.
Since raising our sons on this site we are proud that our eldest is now also a first. He has established an eco-hair salon on our site.
We are just ordinary people having fun trying extra-ordinary things! After 26 years the lawn was finally extinct. It had been replaced by an abundant food forest.
As the children grew we renovated the home using recycled components. Then we created an environmentally friendly office. We started to reach out and become an active part of the community. But we still had time to spend on experimental projects like the upscaled rocket stove.
Living on the Edge
Location: We are located in an old mining village near the university and industrial city of Wollongong. There is a working mine at the top, a school, a pub, and a small Church with a cemetery. Near here was where Koalas discovered white man. In the great depression, Koalas were hunted to extinction regionally. Recently some have been spotted but the water in most of the creeks on the hill has disappeared due to the impact of long wall mining below. The local mine also is the site of our nation’s first industrial disaster in 1902 where more than 90 workers were killed due to open flame style gas lamps.
Aspect and Climate: The ideal slope in our climate would be nor-north-east. But this site is sloped to the west with limited solar access or wind. When we bought the site, the soil was severely compacted pasture with some mature orchard trees. Most years, there is good rainfall year-round. Minimum temperature is 4c, Max temp is recently 40.2c.
Site Size: 1 acre (frankly this is too big for a small family and it would be better to be part of an intentional permaculture village). In a nutshell, ours is a sloped, shady, humid and warm site with valley breezes.
Site Analysis and Sectors
In Permaculture design, we do a sector analysis to learn where the different natural energy sources are on the site. From this, we work out what is the best use of the available energy.
Natural Oddities: Fungi and lichen, self-seeding trees including strangler and sandpaper figs carried by a wide variety of birds (wrens, bower birds, Kookaburras, Cockatoos, King Parrots, Owls, Cat-birds and Brush Turkey). The Cockatoos and Flying Foxes are active pruners and eat fruit that is well out of our reach. Some years they destroy more than we welcome.
Occasionally, King Parrots damage delicacies such as snow peas. Wonga Pigeons and Satin Bowerbirds love to eat any freshly planted seeds . So, we now have two anti-aviaries for growing salad greens.
Other residents include Sugar Gliders, lizards, water dragons and larger possums. Flying Foxes come early in summer and eat a lot of the fruits and berries. Other visitors include Brush Turkey, Echidna, Native eastern long neck tortoise and, of course, snakes (including the golden crown), butterflies, frogs and froglets (including Perons Tree frog), insects and spiders. Non-natives include feral deer, neighbours cows, dogs, chickens, mice and sometimes horses.
Site history: The site had a few very large and bountiful plum, peach and apple trees. They were about 80 years old. At the bottom of the garden lies a small, natural wetland, which has been preserved for the diversity value and as a good firebreak. The land use had involved market gardening, cattle, horses and a poultry farm.
Focus on Regeneration
There was a history of toxic sprays used on this site. So, we avoided growing and eating tubers from the soil for the first 15 years. We have managed all weeds (see more about the weeds below) without any chemicals.
Soil type: When we started here the soil was badly compacted, potters clay. It still is rock-hard in many areas. The acidic soil has been improved by the addition of humus (sheet mulched beds with worms underneath).
Short History of Site:
Our Permaculture site has been in implementation since mid 1993. we started when a drought broke and our seedlings were old enough to plant out. Most of the upper garden beds are the zone 1 and 2 mixed herbs and vegies under orchard trees. These garden beds were made using Esther Dean’s no-dig method without soil. These method helped combat Kikuyu an invasive grass as well improve the heavy soil structure.
The lower section has a steep slope but still we used sheet- mulch. By the 10th year, the trees were mature enough to survive the next drought without any hand watering.
Once we had implemented half our original plan the system had evolved to show more potential and new challenges. We were moving into a dual existence: expansion of the implementation and some maintenance of the established area. Shade and food was created in just 2 years which gave us quick rewards. In 2006 we embarked on a solar passive extension of the house. The new shape of the house formed a nurturing windbreak and suntrap and immediately the Mangos were able to hold their fruit better.
The Layered Food Forest
The existing mature canopy species of this site included: winter citrus and summer prunus fruits, a large Sycamore and Pines, Red Cedar, Grevillia Robusta (to be removed as fuel), and Kurrangong.
Over the decades, the existing tall trees form the structural framework of emergent trees. But there are new emergents such as palms. Tall grasses include Clumping Bamboo (7 varieties) and Bananas (dwarf, yellow, sugar and red).
The main canopy species is a variety of black, pink and white Mulberry (different varieties) which we use for fruit and for many years kept silkworms. We like mulberry because it doesn’t get fruit fly, the poultry, birds and water dragons love it. And there is always enough for us and friends.
The remaining trees vary in height. They include Blackbean, Davidson Plum, Eugenia, Gingko, Maple, Mango, Coffee, Avocado, Jackfruit, Wax Jumbu, Finger Lime, Olive, Tamarillo, Tamarind, Carob, Canistel, Pomegranate, Jaboticaba, Persimmon, Lilly Pilly, Malay Apple, Custard Apple, Guava, Native Rosella, Paperbarks, Fejoa, Lychee, Quince, various Figs, Longan, Babaco, Irish Strawberry Tree, Ice-Cream Bean, Jak Fruit, Bunya nut, Apple, Chestnut, Macadamia.
Shrubs include Hibiscus (edible flowers), Tea trees, Camellia sinensis (Tea), Lemon verbena, Lemon and Aniseed Myrtle, wormwood, various Sages, lavender, hazelnut, native raspberry, lychee, Jabuticaba.
Understorey plants include: loganberry, strawberry, raspberry, blueberry, arrowroot, taro, Yacon, sugarcane, monstera, and mixed salad greens. tomatoes, spinach, lettuce, and Asian greens. Living Mulch plants include: warrigal greens and sweet potato. There are numerous bulbs, Peruvian ground apple, jerusalem artichokes, arrowroot, potatoes, onions; and culinary and medicinal herbs, low sage, lovage, aloe vera, mints, cardomon, tumeric, rosemary, lavender, lad’s love, rue, wormwood, bromeliads including pineapple, ferns, and native palms (including walking-stick palm) and orchids.
Water Plants include: taro, watercress, water celery, kang kong, water chestnuts, lotus and Thai basil.
Climbers include Passionfruit, Kiwifruit, and Epiphiliums (Dragon Fruit), different varieties of grape, and Choko. Smaller tropical species are thriving in micro-climates. Much of the surplus is given to workers and their families. There are some mature trees that will be succeeded by edible species. Rare lumber is gifted to woodturners. Whereas prunings are commonly used as garden edging or fuel in our wood-stove.
The most prolific food plants are: chilli, tomato, mulberry, sweet potato and grapes.
Our Special Interests: In the early years there was a strong emphasis on rare and heritage non-hybrid breeds. We support Seed Savers Australia. Now the system has become more self-seeding and self-governing. We have some unusual species to share such as the highlands Custard apple (Annona cherimoya sp.).
Integrated Pest Management:
Ducks helped control snails in the early years, but we have learned that they are very vulnerable to dogs. Geese deter dogs. The other pests are cabbage moth and Stink bugs on citrus which are controlled by hand and the use of Neem oil. Fruit fly requires yeast baits and the chickens to eat infected fruit. After years of struggle to combat fruit fly, Bill Mollison suggested that we “simply grow what fruit fly don’t eat” and that works for us. The Chickens are trained at a young age to eat specific weeds. Liquid manure in made in big recycled drums and it converts the most invasive weeds such as Madeira vine into liquid manure.
Old chickens are welcomed on our site to let them retire gracefully. The truth is, the chickens are more valuable as weeders than for their eggs.
An old silkie hen: Ginger was 9 years old when she suddenly decided to have chicks. She hadn’t laid eggs for 5 years but she saw how the others did it – demanded attention from the rooster then locked herself in her own nest and made it happen.
We also pick and use the leaves and tubers of invasive vines as bedding in the poultry houses. The biggest threat to the food forest is Madeira vine (Anredera cordifolia). Because we use no herbicide, our management depends on the chickens.
Our geese protect the chickens from neighbours dogs. In the early years they ate the kikuyu. But it long gone. So we slash banana stools and bamboo for their feed. They also deter foxes during the day but they require strong protection at night. We have some recent problems with deer eating young trees so we now protect the young trees with wire cages and a maze of solar-powered electric fencing. We also cover saplings with tents of stinging nettle and woody weeds. The birds regularly eat our fruit but we have plenty to spare.
Impact of Climate Change
In 2013, the extreme high temperatures began to impact the food forest, the mulberry trees fruiting time became confused. The usually abundant and reliable crop failed until 2020. Grapes shrivelled on the vine. But not those grapes the were hidden under the leaves. During 2016-2018 the mulberry trees fruited twice a year because the winters were too warm.
Wollongong traditionally has 6 seasons. We would always experience a false spring around August, just before the winds. The mulberry would normally fruit in mid-December. But they started fruiting in the false spring, and again in mid-December. Neither crop was palatable. Then, finally, the mature trees adapted. This year the mature trees fruited well for the first time in 7 years. They fruited in late November before the heat and after the windy season. Many of the younger trees fruited in the conventional season and got dried out. Some varieties faired better than others. Luckily we had many different mulberry varieties.
Planting and Harvest Plan
We plan for continuous tree planting of endemic species as well as new varities of rare edibles. At first, we would plant at the rate of one plant per day. Most weeks we would start new beds, each day we could collect food. Now, we rarely plant new plants, sometimes we might start some new seed in pots and every day we can find something to eat in the garden. We often share produce with friends and relatives. Often other people share with us in return. After just a few years implementation there were over 60 different edible tree species and varieties, over 160 different edible and medicinal species and varieties of herbs, bramble berries, vines, shrubs, and tubers.
Each new planting get watered daily for a week, then once a week for a month, then once a month for a year. This is our approach to test for suitability and hardiness. Some plant species did not thrive with our YOYO [Your On Your Own] approach. Perhaps they were not given the ideal micro-climate and the soil was probably inhospitable. But many plants did thrive including the rare tropical and bush-tucker plants. The native orange shrub and native raspberries are comfy.
After 25 years the soil was finally black and friable. The garden beds had risen with organic matter. The edges on the gardens needed to be fortified and there were new plantings of shade-tolerant plants. We were pleased to learn that a lot of bush-tucker plants like shade. These plants helped to fill the understory.
‘Weed’ Management and Uses
Our definition of a weed is a plant that “does not respect diversity”. These weeds include Madeira Vine (which can collapse whole areas of rainforest), coral trees, Kikuyu and turkey rhubarb, lantana, croften weed and non-native wandering jew (white flowered).Fleshy invasive plants such as Madeira vine and grass are controlled well by chickens.
Paul has noticed that lantana keeps Madeira vine out. Woody weeds such as Lantana are manually removed and replaced by shrubs to keep soil and wildlife protected. Invasive trees such as Privet and Indian Coral tree have strangler figs in them, have been ring-barked, lopped and the branches piled up off the ground. We have used fire in the stumps to finish them off. We re-use all removed material either as ash, liquid manure or fuel. We do not export material. Weeds work well to mine minerals so we keep our mineral on site. We have found various uses for invasive plants. Most woody weeds such as lantana and privet are cut and burnt in the fuel stove. Some are dried in raised piles on top of tarps so they can’t seed, then later used as mulch. Fleshy plants are put into the poultry house – nothing survives in there! We weave a tent of woody weed branches (not when they are in seed) to protect young seedlings from the chickens and Wonga pigeons.
Our Fuel Stove heating system
Our Fuel Stove and our hydronic heating system are our only domestic heating. Here is a picture showing some of the features.
One of the most important developments for us in using a fuel stove is learning how to reduce effort in providing fuel. We cut and stack the wood only once. We cut dried branches with either our electric chainsaw (we use 100% green electricity) OR a drop saw, we position our bins so the fallen piece falls directly into metal bins. When the bin is full, we place a lid on top and when we required we dust down the bin, and trolley it directly beside the fire. We use old decorative copper fire covers to cover the ugliness of the bins. This method ensures that we stack the wood only once. We have bought metal bins whenever we have found them at recycled shops. Some cheap steel bins need to be stored under cover to reduce possibility of rust.
Our Hydronic Heating System
Our Solar Cooking
Even though we are solar challenged, we get enough sun to cook on sunny days, the temperature in the oven gets up to 115 which makes the best porridge, Curry and Italian sauces. We love cooking with the Solar Oven, you don’t have to monitor it much, except to rotate the oven because this is a basic model. We don’t have to stir, it requires no cleaning (only once did it boil over) AND it never burns! It has no moving parts to break down and was made in India. We bought it years ago from Rainbow Power.
Who Manages the Site?
The regular work involves animal care, mulching, planting, cuttings, grafting, seed management, harvesting. But as Ted Trainer said, it isn’t work when you’re having fun. Most of the site management is done by April Sampson-Kelly, sometimes by Paul and Ryan and occasional student workers. All maintenance and harvesting work is part time and average of just 3 woman/man hours per week. There is little heavy work as the garden is designed to be worked by less-able and small persons. Heavy work such as tree management is contracted to professionals. Paths run mostly along contour, they are covered in recycled terracotta and only require raking. Garden edges are recycled bricks, pavers and fallen logs. The paths can accommodate large carts. Materials are light and transportable. There are ramps rather than steps wherever possible. Some workers have been students who have studied with us in our limited work-learn exchange program.
