What you need to know

Although potato vine 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.


Forest, forest margins, gardens.


Seeds dispersed by birds. Vegetative spread. Human-mediated dispersal through dumping of garden waste and deliberate plantings.

Impact on environment

Can form dense infestations, 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.

Recommended approaches

Physical control

Method: Cut vines and leave upper stems to die in trees or dig out.

Plant parts requiring disposal: All parts (except vines if left to die in trees).

Disposal options: Compost in a composting weed bag or remove to greenwaste or landfill


Biocontrol is currently not available for this species.

Community agrichemical control recommendations

No qualifications: Cut stump and paste freshly cut base of seedlings with glyphosate gel. Foliar spray with 100ml glyphosate green per 10L of water.

Certified Handler/Experienced agrichemical user: Foliar spray with 100ml glyphosate green per 10L of water and 20ml penetrant.

Caution: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.

The scrambling vine can grow into native trees and grow over their canopy. As the vine starts to block sunlight the native trees can collapse and die.
