Seeds dispersed by wind, water and soil movement. Vegetative spread from stem fragments. Human-mediated dispersal through dumping of garden waste.
Impact on environment
Smothers trees and causes canopy collapse, or forms a dense groundcover mat suppressing native vegetation regeneration.
Cut and pull vines away from desirable trees and native plants before foliar spraying. Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
Method: Dig out.
Plant parts requiring disposal: All parts (except vines if left to die in trees).
Disposal options: Remove to greenwaste or landfill if practical.
Biocontrol is currently not available for this species.
