It took a while but I have learned to love Sunchokes. Undoubtedly the easiest and most prolific vegetable of them all. But what to do with them ? Boil them, roast them, grate them into salads, slice them into stir fry. I use them mainly as a filler. They thicken soups and stews and I mash them up with my spuds. Very economical. they don’t have a long shelf life (which is why they are ridiculously expensive) so I tend to leave them in the ground until I use them. If you have a lot of sunchokes - and you will - you can be brutal when you peel them. But keep the peelings out of the compost or you’ll end up with sunchokes everywhere ! Warning : They can be ‘noisy’. Not recommended for date night or before attending the cinema.

My Jerusalem Artichokes had very few tubers. Almost nothing. The soil is semi-sea sand in a winter rainfall area. The colour of the soil is like sea sand. What can I add specifically for Artichokes?

Buy in some good soil and add compost manures etc.

An old timer told me if you wait until after the first frost to harvest the tubers they cause much less flatulence. He said before the first frost they call them fartichokes. : ) Planting for the first time this year and will definitely apply this advice.

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