Where can I get Jerusalem Artichokes in WA? I live on the edge of the desert and don't get to Perth very often. I have only seen them once in WA. I bought those and they grew well. We had a few meals out of the pot I grew them in, but unfortunately my wife threw away the ones I was keeping for the next year's crop. I have found suppliers in the eastern states but they can't supply to WA because of the quarantine restrictions.

If you go to website agric.wa.gov.au click on crops - under horticulture you will see vegetables - click on it. Click on Artichokes and then click on the heading - you will read all about how to grow them. I would try ringing/email the WA veggie growers association or similar and try and find out where to buy from. OR try and find a green grocer who might sell you some and post it to you. Or a friend or someone who lives in Perth. Try these sites - Australian City Farms and even Remote Indigenous Gardens network. Good luck.

Does anyone have any JAs at this time of the year? I'm looking for up to 15 kilos but any amount ok. Jan 2018

Hi Phillip, I have 15kgs of JAs if you are still looking. Growing beautifully pretty much in the deep south. Will still have then in Jan next year.

I live in wa and found some shriveled up chokes at my local iga. I planted them and thought they had died but eventually they popped up and grew. I planted out all the tubers the next year and kept expanding my crop.That was 3 years ago. This year I have planted close to 200 tubers and gave away many more. They grow well here, just need to keep them watered in summer and you will be rewarded. To store them I layer the chokes with coarse sand in a bucket with a lid and give them a spray of water if the sand gets really dry. I am happy to share them if you live in perth.

Hi Leanne. Thank you very much for your information. What would be the best time to plant them in Perth. Can you give me some tubes? - Chi

I have grown Jerusalem artichokes - sunchokes - for two years. What got left in the ground last Fall grew in the late Spring. After two days of below zero temperatures this week I harvested more than 20kg of tubers from about 15 plants. From reading articles and from growing them I learned I cannot find all the tubers when I dig in the Fall. They must be harvested in the Fall, no tubers will form until day length is less than night length.

I planted a couple of JA's in spring and about 8 weeks ago they shot up with lovely yellow flowers. I cut these off fairly quickly hoping the growth would go back into the Tubers. I am guessing i could dig some up, but i would like to also move some of the tubers to another spot. Can i do this now or should i wait until the spring?
