Hi Sharon. I just dug up some yacon today, so have tubers ready to propagate and plenty more in the ground. My patch is near William Bay, 15km west of Denmark. I don't get to Albany much, but do have a list building up so may be in a few weeks... Let me know. Dwayne 04 2882 0660

I live in Adelaide. Can you grow Yacon there? Any advice on growing and where to get the rhizomes/tubers to plant?

Read the article here about growing it. Try the internet for buying - Diggers Club may have it.

Chris grew them in Armidale, (cool/mountain zone) so you should be okay

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?

Mary, Waldecks currently have Yacon for what appears to be much less than the private sellers & they are healthy plants.
