Thanks Mike, yes I know to eat the tubers [luv them, my Father always had them in the vege garden-many years ago] think from your answer I may have watered too much. Was hoping as they had grown so tall that the tubers would be more, but...... I have read somewhere since posting my query, that if one stops them flowering a bigger crop is produced?

I'd also be keen to have some tubers for growing if you still have some available (have fond memories of eating them as a kid from my fathers large garden). Happy to pay postage. Thanks

Ask around nurseries or go on the internet and try and find garden clubs in NZ.

what state or place is the best place to grown sun chokes. we are thinking about growing them commercially and what to know if we need to move or what the best area is.

Could I grow Jerusalem Artichoke in the desert? Any suggestions?

In answer to those seeking advice about where to buy Jerusalem artichokes in Cape Town: I bought some Jerusalem artichokes at the Vineyard Deli, Kenridge, chopped them into small pieces and planted them in a large wooden container. The plants are now (October) about 50 cm high and not flowering yet, but looking extremely green and sturdy.
