Looking for starter for Yacon. I grew it in Peru and was a wonderful crop to have! Any leads?

Maybe too much fertiliser and are they in full sun or shade.

Is it too late to plant my yakons now. How do I keep the plants alive if it is too late

No, it’s just the right time to plant the rhizomes or plants. I have some if you need them. I’ll have to find out how much postage. I live in the Bay of Islands.
