My Sunroot has been growing for about 5 months and is now 2 metres in height and flowering boldly. Do I wait.for the flowers to die off before I dig up the roots? They are extremely healthy. Steve

Wait for the flowers and the leaves to wilt and die off. Once they're all going brown, cut back and dig up the roots.

It looks like my first yacon planting has been very successful, which means I’m going to have more than I can eat while fresh. Any hints on how to store the harvested roots to last for a lot longer?

Layer them in cardboard boxes with newspaper in between layers and keep in a cool place, like a garage. If you have damaged tubers keep them in the fridge.

Is it too late to plant Yacon in Brisbane in September? Also, could you please tell me why, after about 11 months, the stems of the Yacon I planted last year had still not died back. The crop was small, I no doubt needed more organic matter. Thanks so much Kind regards Christine
