It is recommended to leave the tubers in the soil, they will grow by themselves when the climate allows them to.

So if I've just been given tubers (good gardener but never grown them before), they need to be stored like other tubers (spuds/kumaras) over winter? I have a couple of areas on the north side of a stucco house that definitely doesn't get frost - has anyone planted now and managed to overwinter them in the ground ok?

Mike, you can leave the tubers in the ground in warmer areas of NZ, we have done that in Northland. In fact it is difficult to find all the tubers, so they will probably shoot up in the Spring even if you have light frosts.

how do you keep artichokes for the following year for replanting >?

I know it's late but was looking up more info on them and saw this. I store them like I do bulbs, in a small cardboard box with air holes in a dark cupboard in the shed. I normally harvest through autumn and plant next years through spring. Don't know if it's the best way but works for me.

I just leave a few tubers in the ground. They regrow in the spring so long as they get a bit of water. Frost doesn't stop them.

I've just dug up my tubers, in early April - a bit prematurely it appears, as I believe spring is the best time to plant them, August to October. How should I now store them so they won't rot or dry out till then? Or should I just replant them now??

I would just put a few back in the ground. They'll regrow in spring. Very hard to kill.

I keep mine in a plastic bag at the back of the fridge... checking now and again to make sure they don't get wet. They last for months for eating (but I haven't tried replanting those).

I am growing J.Artichokes and they are 2 metres tall and still not flowering .They grow taller than 1.5 metres for sure I usually pickle them and they are delicious. I havent noticed any flatulance,may be the pickling process helps.
