Management Notes (for the Swan NRM Region)

General Biology. Growth form. Shrub/Small tree. Reproduction. Seed. Dispersal. Water, bird, ants, slashing, soil movement, garden refuse. Time to first flowering. 2+ years. Vegetative regeneration strategy. Occasionally resprouts. Does not produce root suckers. Seedbank persistence. Long, 10+ years. Fire response. Fire stimulates mass germination of seed and generally kills adult plants.

Notes. Soil disturbance triggers germination.

Additional information. Origin. New South Wales (Cootamundra). History of use/introduction. Garden escape.

Suggested method of management and control. Hand pull seedlings. Fell mature plants. Young plants may occasionally resprout. Apply 250 ml Access® in 15 L of diesel to basal 50 cm of trunk (basal bark), or cut and paint 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.
