If you go to website 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

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.

Where can I buy them in the Sandton, Fourways area? Thanks

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 and, both of these sites usually have tubers available when in season.

Can tubers be planted in the fall and harvested the next summer like I do with garlic. We usually have a late spring so it's hard to plant until at least June.

Jerusalem Artichokes can definitely planted in the fall. Studies show that fall plantings are, in fact, better for production as it promotes an earlier start for the plant.

No one responded so I will. I do not know for certain. I shop at farmer's market where 2 organic farmers grow and sell these. Both know I grow much of my own food. The guy I normally buy these from never suggested I plant any.. He had ended for the season and I purchased from the other grower. She was telling everyone to plant some of what they buy. HOWEVER she often sales pitches to clear out stock. Also they are zone 4 - 5 -along the river near Kamloops.. I'm at much higher elevation in an unpredictable area. I long ago quit buying zone 4 plants due to cold snaps that hit every few years. I'm going to try a couple roots this fall if I can get them in this week. (end Oct, 1st of Nov -the next snow might stay). If you have access to them I suggest you try a few too. All the local growers who are at warmer elevations than I start their garlic in the fall and say it needs the extra growing time. These may need the settling in time too. Trial and error is the best bet in these climates. I'm on a hillside and after 30+ years still marvel how some plants do well in one area but not 10-15 meters away. I think it's related to underground moisture. Good luck!
