Yacon is perennial in sub-tropical/tropical areas. Save some root pieces and treat as an annual in other areas.

Grows into a large plant ( about 2m/6ft) with flowers similar to sunflowers and Jerusalem artichokes.

The plants die down after frost but the roots are sweeter. To store, dig and dry out for a couple of days in the sun if possible. Store in a dry, cool, not freezing and dark place.

Any roots left in the ground will grow the following year except where there are frosts.

Culinary hints - cooking and eating Yacon

The large roots can be used raw in salads peel and chop. Sprinkle with lemon juice to prevent browning.
'In the Andes, they are grated and squeezed through a cloth to yield a sweet refreshing drink. The juice can also be boiled down to produce a syrup. In South America the juice is concentrated to form dark brown blocks of sugar called chancaca.' (Green Harvest)

This is my second year of growing Yukon I was just wondering if anybody knows if I can leave them into the ground to store the fruit for a few months like a potato thank you

Depending on where you live - I wouldn't leave them in the ground if a chance of rain/heavy rain - they would rot. We are having the wettest Oct on record where I live. Maybe store in a box with sand or just store them in a cool/dry place.

Apologies for not checking my post...autocorrect put 'compacted' soil. I thought I typed 'composted' soil. I would imagine that compacting the soil would not be that great for a tuber! Sorry folks!

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.

I have been looking for a supplier of the rhizomes for a few months & have just stumbled on your page. Can someone let me know where I can get them (I am on the Gold Coast) I will need to build up a bed as we have very sandy soil. Any assistance will be gratefully received.

Hi Lyn, I live on the West Coast and I brought my first Yacons from Dayleys fruit tree nursery NSW. They are great people to deal with and have a great web site. Regards Robert Devine. 0400614698.

Type in Yacon for sale in Australia in google - Ebay - Gumtree - other companies - green harvest has very good info about them. Look around to get a good price. Some places want 10-15$ and the same again for postage. Could try Bunnings.

Hi - I too would love to take you up on your offer. I'd love to try growing some Yacon after reading about the great health benefits of it. I hope you still have some to spare. I also live South of the river. Hope to hear from you. Cheers, Brenda.
