Hi, I've just received some yacon rizomes and live in Geelong, Victoria. They are currently wrapped up in coco fibre and peat moss or something similar and in a plastic bag. I want to plant them in pots. If the best time to plant is October / November, what can I do with them now? Can I store them the way they are or should I plant in pots and keep under cover so they won't get frost on them? Thank you

Dear Ellen, if you still have any Yacon roots I would love one to grow. I can swap you for another plant of your choice if you like. I live in Sydney. If anyone else has one they would like to give away I would very much appreciate it. Thanks very much Jan

I received information that the properties from Sunroot taken orally are a rejuvenation to life healing or giving relief to many ailments including arthritis, diabetes, rheumatics, cholesterol etc. Seems too good to be true. Can you support their claim? I would like to grow it, can you help me?

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.
