I live in Redland Bay Qld and I am finding it impossible to buy or find Jerusalem artichoke tubers. I so desperately want some to plant. Could you please help me find them. Sincerely Marlane Rogers

Hi I have been growing them for 20 years plus. Sell my excess on eBay And Gumtree. Sold 35kgs this year (and I eat/ate a lot myself! Lol) they are very productive and so easy to grow

There are currently several people and nurseries selling Jerusalem artichoke tubers on EBay Australia. I've just bought the cheapest lot from Sydney NSW.

I could send you some - but pretty sure that’s not possible / legal from Victoria into QLD?

Can I grow sunchokes in containers ? If so does it require anything special and when is the best time to plant?

I got a lot from my grandfather one year but made the mistake of dishing them up to a group of friends just before we went to see a play..... those who have eaten them before can imagine the consequences. Really yummy, but unfortunately they do have a side effect not compatible with a quiet live theatre.
