Even gardening pros like Matthew Evans struggle with soil health every now and then. Healthy soil yields healthy crops, which, as any good home gardener knows, can be the difference between an outstanding meal or just an okay one. But juggling rainwater management, climate and garden maintenance with the overarching goal of living and farming more sustainably can present challenges for all types of gardeners, urban or rural – even at Fat Pig Farm in Tasmania’s Huon Valley.

Hannah Moloney, co-founder of Hobart-based Good Life Permaculture and former Gardening Australia host, is chock full of simple, DIY techniques for home veggie growers looking to optimise the quality of garden soil, particularly through slowing, spreading and sinking nutrient-dense rainwater.

Make your home garden thrive.

Moloney has coached Evans through the benefits of digging off-contour swales (like mini trenches) and planting trees as a regenerative water management technique. These simple gutters are used to trap rainwater and allow it to recharge into subsoil to restore overall health. They’re also easy for you to implement yourself at home.

“Water and nutrients are critical to a healthy landscape,” Moloney tells SBS. “Strategic earthworks like off-contour swales can accelerate landscape health and productivity. Off-swales work particularly well in cool, temperate climates because they slow and sink water into the soil – instead of it quickly running off the landscape – and catch and store nutrients in that area like leaf litter, animal manures, any organic matter.

“This organic matter can be caught in the swale’s shape and break down in place, providing food for soil biology to cycle throughout the landscape.”

The Fat Pig Farm site slopes, meaning hillsides were dry at the top and boggy down the bottom.

Off-contour swales work especially well on Fat Pig Farm as it’s positioned on a sloped site . Swales dug into one side of the gully can harness rainfall and enrich the whole hillside with water and nutrients. But that’s not to say the technique can’t work just as well in your back yard.

“In our garden at home, we’ve shaped some of our pathways to be off-contour swales, where they can catch and store rainfall and organic matter and sink it into the landscape,” says Moloney. Digging swales in your garden is a low-tech, easily achievable way of harvesting nitrogen from rainwater, making home-grown veggie patches sing.

And that’s not the only permaculture hack hiding up Moloney’s sleeve. Here are four more tips for getting the most out of your veggie patch, whether it’s a tiny inner-city plot or part of a sprawling acreage.

Plan, plan, and plan some more

“If you’re starting from scratch, take some time to do a design for your garden,” Moloney says. “This will help create space that meets all your needs, and is more likely to avoid mistakes which can cost you time and money.”

Do research on sites like Good Life Permaculture, and perhaps even consult an expert for preliminary information and ideas.  

Watch your waste

“Compost everything,” says Moloney. “Seriously. There should be nothing organic going into your bin. Compost everything and cycle those nutrients back into your productive garden to feed the soil and plants.

Thankfully, there’s no shortage of resources on composting – even if you’re a complete novice. Read our ‘how to’ guide here.

Week 5: How to compost
Compost is a gardener’s best friend. If you added it to your soil when you set up your vegetable garden, you may have already witnessed the benefits. It’s the best soil conditioner you can get, and when you make it yourself, it’s absolutely free. Not only that, when you recycle your own organic waste at home, you reduce the amount of waste going to landfill as well as the community costs in collecting and processing wastes. Composting is a simple thing we can all do. Even if you are in a flat or unit, you can recycle your kitchen wastes using a worm farm or Bokashi bin.

Mix it up

“Diversity of plants is key to a healthy garden. Grow a range of herbs, salads, vegetables and fruits strategically. This diversity will help prevent pest invasions and provide a broad yield across all seasons,” Moloney says.

Pace yourself

“Start small and then gradually increase your garden’s size as you have the time and capacity to maintain the garden,” Moloney advises. “Sometimes people struggle to maintain large gardens as they’re busy with work or family. Just have a small garden if this is the case, and make it a really intensive one that produces well.”

Week 4: Growing fruit
No matter where you live in Australia, you can grow some of your own fresh fruit at home. The true joy of home growing is harvesting fruit at its peak ripeness and sweetness. But it’s not just the fresh produce - fruit trees make wonderful shade and climbing trees, some are useful for creating privacy while others are just beautiful trees to look at. It’s true, Aussie backyards are getting smaller, but there are still many ways you can enjoy growing a range of fruit, even in small spaces.

Gourmet Farmer: Asparagus & seasonality
This is the hungry patch. The time of year when the winter crops have all but finished, eaten (by us or the slugs"¦), gone to seed, or like the garlic, not ready to harvest yet. Thank goodness for lettuce. For leeks. For the first of the broad beans. And a big special thank you to the asparagus, which is in its fourth season in my home garden. Asparagus is the miracle green that bridges the gap between winter crops and the peas and beans that mark late spring.
How to grow: Stone fruit
What could be better than sweet juicy stone fruit picked straight from the tree at their peak of ripeness? Stone fruit are perfect for home gardens; they look beautiful in spring blossom and in summer provide the most mouth-watering crop. They’re not for the lazy gardener though. Stone fruit need close attention to feeding, watering and pruning and there are lots of pests and diseases that can upset your crop. But if you’ve got the right climate and you’re prepared to put a little effort in, you will enjoy the most satisfying home harvests.
How to grow: Brassicas
Broccoli, cauliflower and Brussels sprouts are all members of the cabbage family, often referred to as 'brassicas". These vegetables are simply delicious, and crammed with vitamins and minerals and other health giving properties. Broccoli and cauliflower are the flower heads of the plant that are harvested just before the flowers open. Brussels sprouts are the tight, swollen leaf buds that look like miniature cabbages forming progressively along the tall central stem of the plant.
