Orange Hawkweed


The following page is a brief summary of information available on the DPIPWE website regarding Orange Hawkweed control. For more information view here

Non-chemical control

Physical removal

  • Small infestations of Hawkweed can be removed by digging out the shallow-rooted rosettes.
  • Ensure the whole plant, including all roots and runners, are removed, as plants quickly regrow from fragments if any pieces of runners or roots are left behind.
  • Be careful when removing flowers and seedheads so that seeds are not accidentally dispersed. Flower and seedhead material should be burned.
  • Mowing can prevent seed production by removing flowering stems. However repeated mowing can stimulate growth of runners and worsen an infestation.


  • Establishing a competitive, well managed pasture or lawn area can reduce the size and impact of Hawkweed infestations.
  • On cropping land, establishing a competitive crop can control Hawkweed, especially where herbicides are also used in the cropping system.

Chemical control

Use herbicides in accordance with label. Refer to APVMA permit PER13160 where herbicide is to be used in non-cropping and bushland areas

Application method

1. Spot spraying
