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!

I have just received JA`s and want to plant them but we are into the colder months , should i store them and if so how or should i put them in the soil and wait for them to come up ? i dont want to lose these ive been searching for them forever

I would store them in a pot filled with damp sand until spring. If you leave them out they will shrivel and if you plant them they may rot unless you have good drainage. Once established they are virtually indestructible and would survive most winters.

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?

You could 'raid' a few now if you wanted to. They would be riper when the plants start to die back for the winter. Even though they are just about indestructible it would be better to transplant them in the winter when they are dormant.

I planted Jerusalem Artichoke in February. It is now April and the plants look healthy but have only reached about 1 mtr in height. They reached this height quite quickly but have not moved for about 4 weeks. Is this natural? Thank you.

There could be a number of reasons including; a dry spell, cooler weather, planted late in the season, etc. but if your plants are healthy I don't think you need worry.

Like most of the queries, where can one get JERUSALEM ARTICHOKES? I'm kinda old now but remember my father growing them in Pretoria in the 1950's the goggle eyed face you get when asking at a greengrocer or even a nursery tells all.
