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

My friend’s yacons are flowering everywhere and my - not even a bud, same as last year. What have I done wrong.

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.

Just doing some research myself, and I found this comment on the Koanga website - https://www.koanga.org.nz/yacon/

Will yacon roots be safe underneath the ground in the winter and be able to regrow again in spring in zone 7a? (Is it Perennial in zone 7a?) Thank you. Pat

Hi Ron and friends, I live in Bankstown NSW. I am interested to grow Yacon in my backyard. Could you tell me where can I purchase the plants? Thanks a ton. Minh
