Management Notes (for the Swan NRM Region)

General Biology. Growth form. Shrub/Small tree. Reproduction. Seed, root suckers. Dispersal. Water, bird, ants, soil movement, garden refuse. Time to first flowering. 4-5 years. Toxicity. Can be toxic to stock. Can cause skin irritation in humans. Vegetative regeneration strategy. Resprouts, produces root suckers, stem layering. Woody structure. diffuse porous. Seedbank persistence. Long, 5+ years. Fire response. Fire stimulates mass germination of soil-stored seed. Adult plants will resprout from base and from root suckers following fire.

Additional information. Origin. South east Australia. History of use/introduction. Garden escape.

Suggested method of management and control. Hand pull seedlings. For mature plants apply 250 ml Access® in 15 L of diesel to basal 50 cm of trunk (basal bark), or drill and fill with 50% glyphosate. Older plants can be ringbarked. Monitor site for recruitment from seedbank. 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.
