What you need to know
Although porcelain berry 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 and riparian margins, canopy gaps, open areas, wasteland.
Seeds dispersed by birds and possibly mammals and water. Vegetative spread from layering. Human-mediated dispersal through deliberate plantings.
Impact on environment
Can form dense infestations, smothering native vegetation and suppressing seedling recruitment.
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: Cut vines and leave upper stems to die in trees and 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
For small infestations: Cut stump and paste freshly cut base of stems with metsulfuron gel.
Basic Growsafe certified:
For small infestations: Cut stump and spray freshly cut base of stems with 1g metsulfuron-methyl per 1L of water. Cut vines at waist height and foliar spray vines on the ground with 0.5g metsulfuron-methyl per 1L of water.
Certified Handler/Experienced agrichemical user:
For medium to large infestations: Cut vines at waist height and foliar spray vines on the ground with 5g metsulfuron-methyl 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.
