Weed Buster Week

From October 7th until October 15th is Weed Buster Week across Australia.This year the programme is designed to raise awareness of the problems weeds cause in farmland and bushland, as well as encouraging hands on involvement in reducing the spread of weeds - eg join a Coastcare or Friends of bushland group.
For other ways to aid the fight against weeds see the Weedbusters website where there is excellent information on weeds, pests, plant diseases and lots more.

The website has fact sheets including those on:

  • Gardening advice
  • How weeds are spread
  • Weed facts and figures
  • Weeds in Australia

These are a few sobering facts I gleaned from the website:

  • 65% of weeds introduced to the Australia landscape are 'escapes' from urban parks and gardens.
  • Six of Australia's worst invasive weeds have degraded over 20million hectares of natural and grazing lands.
  • More than 2,500 species of environmental weeds in Australia are now taking over Australian native vegetation.
  • Weeds know no borders!

From the Weed Busters website there are links to the Department of Agriculture website (click here to view) where there is lots of excellent information on weeds, plant diseases and much more.

As far as the 20 'WONS' species ( Weeds of National significance) are concerned, in Cottesloe only Asparagus asparagoides or bridal creeper is present in small pockets. If you have this weed in your garden please remove it as it spreads quickly!

The Declared Plant list is far longer and Cottesloe Coastcarers work hard on many of these weeds along the Cottesloe foreshore, with assistance from the Town of Cottesloe.

It is good to see that the sale of the declared weed Zantedeschia aethiopica or Arum lily (pictured), has at last been banned across Western Australia.
