Hi there I recently bought some Yacon while down on the coast. I have 2 pieces of the fruit (which I plan to eat shortly) and a large piece of the root/rhizome. How should I store this until I can plant it in September (after the frosts) Cheers Colleen

We are in Bundaberg area Queensland and would like to know if Yacon would grow here and where can we get seed or rhizome pieces. Thankyou for a great article

Hi Jim and Jan. It will definitely grow in Bundy. I have rhizomes (called 'setts') available. Let me know if you still want some.

In July I planted some tubers I got from my relative in the Blue Mountains ...cold up there. Came back to Brisbane and left them lying around for a few days before I got round to finding a big enough garden bag/soil to plant in. Put them NOT too deep in organic compacted soil and in a week or two they shot up. Now in September they are growing very quickly and looking great. The tubers had gone a bit 'soft' before I planted them but all seems to have gone fine...so far. Not sure when they may reach flower and die back. Excited to see what happens.
