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)

If no success try Boondie Seeds (lives in Armidale NSW) - they have them but sold out at the moment - contact her to find out when she might have them back in stock. Sometimes she has stock when the website says sold out.

We had a great crop (considering 1st year in the ground.) This 2nd year the plants have flourished but haven't flowered. The plants are just beginning to feel the cooler monthes (we water but very dry). We have had no flowers this year. Should we be concerned? Thanks for any tips!

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.
