What you need to know

Although Port St Johns creeper is not a legally declared pest plant, it may still be invasive in some situations. Consider lower risk alternatives for your garden, such as native plants.

Riparian margins, gardens, urban areas.

Sets seed. Vegetative spread from layering. Human-mediated dispersal through dumping of garden waste and deliberate plantings.

Forms dense thickets, smothering other vegetation.

Site Management

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.
