Gardening sustainably just makes sense in this fragile world of climate change and environmental damage. Actually doing it in your own backyard takes a little effort, but in Albury and surrounds more and more gardeners are finding that every step is worth it to create a sustainable garden that not only looks after your plants, and you, but also helps the whole planet.
Reducing Your Environmental Footprint in the Garden
Switching over to sustainable gardening practices goes a long way to building a garden that you can enjoy, admire and even eat. At the same time, you reduce your environmental footprint, by increasing carbon storage, reducing greenhouse gas emissions, and contributing to plant and animal biodiversity. Here are a few tips to create your sustainable garden:
- Plant trees. Planting trees helps to store carbon from the atmosphere into the soil. Trees can also cool your home in summer and let in the winter sun. If you don’t have room for trees at your place, volunteer with a local landcare group.
- Grow your own organic food. Not only does this help to reduce the distance your food travels before it hits your plate, but it also helps to save water and fossil fuels.
- Compost your waste. The less green garden waste and food scraps going into landfill the better, and you get to use the compost in your sustainable garden.
- Take responsibility for your gardening practices. Think very carefully before you reach for the bug spray or synthetic fertiliser! So many good, sustainable alternatives exist — use your compost to help feed your plants, and get worms and insects working for you.
- Help stop the spread of environmental weeds. Find out what plants have become weeds in your area and, if you have them or they pop up, either get rid of them safely or contain them.
- Minimise your use of powered tools. Mowers, blowers and brush-cutters can make life easier, but think about their environmental impact. Buy an energy-efficient mower, mow less often and keep the grass height to about 4 to 5 centimetres — it’s better for your sustainable lawn as well.
- Get the kids into sustainable gardening. At home, at school or in the community, if kids learn the right way from the beginning, they’re sure to keep gardening sustainably into the future.
- Only use renewable resources in the garden. Check the source of gardening materials, and make sure you reuse, recycle and renew. Think about where your pavers, sleepers and mulch come from and how they’re manufactured.
- Create a haven with a diverse range of plants. Not only do you help increase plant biodiversity, but you also provide a habitat for animals, beneficial insects and birds.
- Build your garden for the future, not for fashion. Make your garden climate-friendly and water-wise. Understand your environment, weather patterns and the plants that thrive where you live, not what the magazines dictate.
A Few Essential Tools for Your Sustainable Garden
To create your sustainable garden, some things are just too good to pass up. Compost, mulch and worms all help to condition your soil and retain moisture, and you can get beneficial insects to work with you to keep your plants healthy, sustainably.
- A compost heap or bin: Choose whatever type suits your garden — a three-bay heap for a large property, a classic upside-down-bin style to place in an average garden, a tumble-type bin that neatly sits on a paved area or a bokashi bucket to keep in your kitchen. Mature compost ends up as a delightful humus to use as a soil conditioner in your sustainable garden, or, for the bokashi method, a delicious pickle your plants love.
- An insectary: A garden plot, or even a series of pots on a balcony, with at least seven different plant species of varying heights attracts various beneficial bugs to your sustainable garden. Good candidates to plant include amaranthus, coriander, cosmos, dill, lemon balm, parsley, tansy and yarrow.
- Mulch: To help keep in precious moisture, cover the soil around your plants with the finished humus from your compost or an organic mulch, such as matured manure, pea straw, pine bark, seaweed or sugar cane. Inorganic mulch, such as pebbles or granitic sand, should be use sparingly in a sustainable garden.
- Worms: You can buy or build a worm farm or simply attract earthworms to your soil. Either way, worms produce a fantastic by-product, commonly known as worm castings, or vermicasts, that attracts microorganisms, such as good bacteria and fungi, to your soil so your plants thrive. If you have a worm farm, the worm wee, actually the liquid that accumulates at the bottom, is an added bonus for your garden.
