what time of the year can i plant yacon in the westerncape?
26 Feb 17, John (Australia - temperate climate)
Yacon needs a soil temperature of about 15 degrees Celsius or higher. Plant it about the same time as you would plant tomatoes. It takes about 6 monyjs to harvvest but some roots can be carefully removed earlier. The tops will die off if you get frosts but the roots will be sweeter after the first frost. Trust this helps

i have planted 3 bits of yacon, temps in the western cape in the high 20 s, have planted them in containers as they are sprouting, will hope for the best! jerusalem artichokes grow well in my garden, but they are flowering now

I hope you do well with your yacon. Keep in mind that containers can get very hot on a hot day and also pay attention to watering. A wet, dry, wet, dry situation will reduce your yield. All the best.

thanks for your advice John, I will not let them dry out, I just hope they make enough tuber to resprout in our spring here, having planted them so late!

Where can I buy yacon to plant? Jeanne

I would try - www.organicseeds.co.za They do not list it but may know who would have it. All the best in your search. Maybe a South African gardener will read these pages and help.

Hi guys. Would anyone be able to help me with Yacon rhizomes or tubers for planting. Would really appreciate it. Thanks

Hi Riyaad Was just wondering if you had managed to get Yacon tubers for planting. I am also looking for some and thought that asking you would be a good place to start. Thank you Amanda

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
