It depends what you mean by bulk. I have just bought a kilo on Trade Me from a lady in Napier.

I live in Coffs Harbour, New South Wales. I have just purchased a kilo of JA at our local Supermarket. If I plant each tuba now (June 2013) without any shoots on them, when could I expect a crop for eating? Is the supermarket the best place to buy JA for propagating?

JA's are the toughest of tough tubers. Wait until winter is finished and plant SIX of your tubers. They will grow through spring and summer, flower in late summer (with a wimpy type sunflower (will look wimpy compared to the sunflower you get seeds from). Where I am, in May the flowers finish, the stems die, and the earth heaves up, and one sunny Sunday arvo you dig up about five fold the tubers you planted. PLUS, you don't get them all......... without doing anything at all, for the next 15 years, you have JA's........ Good Luck...... PS Mine came from a supermarket, and I started with a dozen in 2 square meters, I have finally got them down to ONE SQUARE METRE and that's enough for us !! In Coff's you will way surpass me "hands off" endeavours of 15 years................. enjoy !

Jerusalem artichokes can be baked, steamed or boiled and are nice served with a melted butter sauce. If you don't dig them up until the stems have died , you will have less problems with flatulence

I have one plant that is dying off, one just finished flowering - both from last year's crop. I'll be digging tomorrow, yippee. I have always had them roasted or boiled. Love them but yes, flatulence is a problem.

Hello Di I was wondering how much yield you got from your plants I am also a sub tropical grower and considering it was the first time I grew them very happy with my results still picking them and next year will grow 10 times the amount cheers

We started growing them in large raised area because my partner swears by them for his rheumatoid arthritis. Eats 1 raw every day!

Hi, I’m just about to try Jerusalem Artichokes for an autoimmune disease. They are great for good gut bacteria which in turn is good for autoimmune diseases .... heaps of evidence of now that autoimmune plus other diseases are gut related!
