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.

I also found Jerusalem Artichoke plants at Ferndale Nurseries in Constantia, Cape Town!

I originally took free tubers left by a neighbour on the kerb. I planted five in a raised garden bed of one metre diameter. I've harvested about 5 kg of them! I've been giving them away, cooking & eating them, frozen the last batch as well. I call them fartichokes. They're a handsome plant with pretty flowers that don't appear until late summer.

can an artichoke be broken or cut into several pieces to be able to plant more?

Google growing them and go to the green harvest website.

Good afternoon, I've read contradicting info that jerusalem artichokes will and won't grow in the tropics. Can you tell me definitely which is right please. I have tried once to grow them in Townsville with no success at all. Are there guidelines for getting good results in the tropics or are they just not suited to the climate. Thank you Jan

I have a couple of month old one that I got for 10c at Bunnings. From what I have read, they really struggle with the heat during summer. I can attest to the fact that they hate water logged soil. Both of these sound like deal breakers in the tropics. I get the impression they would be the perfect plant for cooler temperate areas. If you are really keen, maybe you could try a single one in a large pot in a shaded and covered area and see if it survives the summer. At least you could reduce soil temperature and the amount of water it gets this way. I assume planting now and getting it established before it hits summer would also help.

It indicates here that artichokes don't grow in the tropics. There is probably a reason/s why - too wet - too hot. If you look at sub tropical it says plant Aug to Oct. That would be the best time to plant. You will never know until you try it.

Can I grew them in zone 5a?

Not sure if you have come right yet, but if not... Jerusalem artichokes will probably not be on sale until the end of the season - at the moment they are putting all the energy into the flower and won't be of a quality to sell. You can keep an eye on www.seedsforafrica.co.za and www.theseedvault.co.za, both of these sites usually have tubers available when in season.
