Rampant climber, with fleshy leaves. Fl. white, Mar to Apr. Along creeklines.
General Biology. Growth form. Vine. Reproduction. Detachable warty tubers on branches, tuberous roots, rhizomes, seed. Dispersal. Water, garden refuse, gravity, soil movements, possibly birds. Toxicity. suspected to be poisonous to livestock. Vegetative regeneration strategy. coppices/resprouts. Seedbank persistence. Aerial & underground tubers, 5-10 years. Fire response. Does not seem to affect tuber growth.
Notes. Vigorous climber, capable of smothering all vegetation. Plants can grow a metre per week in warm, humid conditions. Tubers can be football size or bigger, and can be found up to a metre underground. Weight of vine can crush trees and other species on which it grows, inwardly collapsing the forest margin.
Additional information. Origin. tropical South America. History of use/introduction. Garden escape. Similar native species. Muehlenbeckia adpressa.
Suggested method of management and control. Hand pull seedlings less than 3 cm high; dig out tubers, ensuring removal of every piece; cut aerial tubers from vines before removing plant; cut stems in solution of 1:2 glyphosate in water; stem scrape or drill and fill thick vines - 100% glyphosate (do not cut the stem completely); intensive follow up of resprouts at 2-4 leaf stage 2 to 3 times per year for up to ten years. 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.
