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 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).

My j/a are 3mtrs tall with lovely flowers, and are growing like wildflowers they are absolutely lovely, this is their 2nd season growing. I watered them everyday with plenty water. The tubes are massive. Not eating yet, just want them to grow. I live in Murupara, NZ.
