Sustainable Gardening


  • Think catchment - how does my gardening impact on the broader environment? Is my gardening having a negative impact due to fertilisers, pesticides or landscape materials running off my garden, or weedy plants escaping from my garden?
  • Is my garden a water waster? There are many ways to reduce water in the home garden - see the Sydney Water website for great information on saving water but still having a healthy garden.
  • Don’t forget the natives! Gardens play a critical role in supporting native fauna - see our tips on plants for wildlife.
  • Some plants can escape and contribute to the weed problem - remove weedy plants!

Home tips

  • Compost your green waste and return this rich material to the soil - see our tips on composting.
  • Use mulch to reduce water consumption - see our tips on water-wise gardening. Organic mulches will also supply some fertiliser to plants.
  • Healthy plants require little if any spraying. If you select the right plants and put them in the right location, water and mulch them, you will have fewer problems with plant pests and diseases.
  • Keep an eye out for weedy plants in your garden. Remove them - especially if they are likely to escape from your garden.
