Weed library - Bracken (Pteridium esculentum)


Bracken fern (Bracken) is a native perennial fern that can be found in most temperate areas in Australia.

Bracken has erect, stiff fronds (up to 1.5m tall), that are bright green and coiled when they emerge. As they unfurl and expand, the fronds become harder and darker. Fully mature fronds are dark emerald, green.

The root system of Bracken is extensive with a vast network of rhizomes underground which produces new shoots. Translocation of the herbicide to the root system and rhizomes is vital to maximise control of the Bracken plant.

Herbicide Control Options

Step 1. Select your situation

Control Tips



  • Spray when most of the fronds are fully unfurled (November/December to April/May)
  • The most effective time to spray is late Autumn when the fronds start to transfer food reserves into the rhizomes.
  • Where recommended by the herbicide label, use a wetting agent like Holdfast Wetting Agent and Penetrant to improve control.
  • When handgun spraying, spray to thoroughly wet all the foliage but not to cause run off
  • Spray when the plant is actively growing

  • DO NOT disturb Bracken for 8-12 months before and 6 months after spray application
  • DO NOT spray when the plant is stressed (i.e. Drought, physical damage, insect damage, frost)
