Management Notes (for the Swan NRM Region)
General Biology. Growth form. Tree. Reproduction. Seed, suckers prolifically following disturbance. Dispersal. Birds, water, rats, mulch. Time to first flowering. 3 years from seed, 2 years from suckers. Toxicity. Poisoning is said to occur if 6-9 fruits, 30-40 seeds or 400g of the bark is consumed.. Vegetative regeneration strategy. Resprouts produces root suckers, stem layering. Woody structure. semi ring porous. Seedbank persistence. Medium, several years. Fire response. Suckers prollifically.
Additional information. Origin. China, Japan, Indian sub-continent, south-eastern Asia, northern Australia. History of use/introduction. Garden escape.
Suggested method of management and control. Hand pull seedlings, ensuring removal of all root material. Stem inject older plants using 50% glyphosate, or basal bark with 250 ml Access® in 15 L of diesel to base 50 cm of trunk. Avoid root disturbance until trees are confirmed dead. 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.
