there were about 5 vines growing from tubers.; I dug them out, double bagged them (with soil and tubers) and placed them in my rubbish bin. Requires monitoring - several months ago I dug out several Bridal Creepers close by.
On Monday 18 March we dug out and bagged 5 new vines with bulbs and soil; monitoring must continue. The site is ideal for BC: protected by tree canopy and very high soil nutrient content judged by the weeds growing there (monstrous Paterson's Curse etc...)
