Garden plants are the biggest source of weeds in this country totalling 70% of Australia’s combined agricultural, noxious and natural ecosystem weeds“. (CSIRO 2005 Report ‘Jumping the Garden Fence’). Governments and volunteers dedicate enormous resources to controlling invasive plants that destroy biodiversity.

Weeds in the garden create a chore that needs to be attended to in order to keep our ornamental plants healthy and to make the garden more attractive. When plants become weeds in our bushland and waterways, however, they pose a much more serious problem.

Here are our posts about invasive plants:

  1. I have a question;
    I live in WA (Fremantle area) and would like to grow a hedge with Albany Woolly bushes along my drive way. My concern is that the neighbors plumbing runs along side this drive way and the last thing I want is to have roots upsetting their plumbing. Does anyone know if the roots of the Woolly bushes are invasive?
    If so does anyone have any suggestions for hedging in this setting. It is hot and dry most of the year here.
    Thanks Leny

    • We dont think there is any cause for concern about the roots. If there are salt winds and alkaline soil the following are suggested as alternatives:
      Calothamnus quadrifidus
      Olearia axillaris (less formal style hedge)

      if its protected from salt laden winds and has alkaline soil we suggest the following also:
      Grevillea olivaceae
      Hakea laurina (less formal hedge)
      Agonis Afterdark, Burgundy

      Hope this helps!
