I have grow a Yacon as a test run and it went OK so I have 10 plants in now and they are about 1m high. When I harvest can I just plant the rhizomes straight away back into the ground or should I pot them first?

I am on the east coast of Tasmania and would like to get hold of some Yacon plants. Does anyone have any available? I can collect north or south of the state. Thanks, Tony.

Hi Tony, I am in Hobart and have recently harvested my Yacon and have several clumps of Rhizomes/tubers available if interested. Happy to give away. They grow well here and multiply ++ I acquired my first tuber from a friend in Burnie (they grow well there) ... founder of Food Plants International, which has produced the largest database (fee online) of edible food plants in the world.
