So... any specific techniques for killing this one off? Or shall I wander up there again with a garbag this weekend and just pull out everything I can find (fruits and roots in particular)?
Dig the roots out, he says... Erk, these things have extensive but shallow roots... almost 3m from where it came out of the ground to where I lost the longest root. Did a search around and couldn't see any others - there are a lot of hardenbergia in the area that the leaves can be superficially confused with.
Sorry about that. I must have been lucky with the ones I dug. When there are lots of different plants around I scrape the stems and apply glyphosate, but I didn’t know if you could do that. Plants on Oakey Hill possibly spread from the old School of Horticulture (now Featherston Gardens) in Weston. I reported some from there in 2017 and assume they were removed.
