Management Notes (for the Swan NRM Region)

General Biology. Growth form. Tree. Reproduction. Seed. Dispersal. Wind, water. Time to first flowering. 6 months to 10 years. Vegetative regeneration strategy. Lacks a lignotuber. Woody structure. Diffuse porous. Seedbank persistence. Short, days-1 year. Fire response. Hot fire will kill adult plants. Prolific germination of seed follows fire.

Additional information. Origin. South eastern Australia. History of use/introduction. Garden escape, restoration plantings.

Suggested method of management and control. Hand pull or dig out seedlings or smaller saplings, ensuring removal of all roots. For mature trees or for saplings too big to hand pull apply 250 ml Access® in 15 L of diesel to basal 50 cm of trunk (‘basal bark’) or cut and paint the cut stump immediately with 100% glyphosate or drill and fill with 50% glyphosate. For any re sprouting foliar spray with 1.5 % glyphosate or 4mL/1L triclopyr. Alternatively cut down the tree then remove the stumps to a depth of 300 mm below ground level to prevent re-sprouting. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
