Bunnings sells an 8-pack (Bloomin' Bulbs range) that is available in most stores. (I checked availability for Mackay recently and noticed that a bunch of stores all the way up the coast stocked them as well.) If they don't have any, it might be worth checking Mitre 10. I recall the store in Sarina having some and suspect that it might be something that the chain stocks on a regular basis. Best wishes in finding some bulbs near where you live!

I am ready to harvest my Jerusalem do I leave them in the ground to harvest them again in September or do I pick them now to be planted then?

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.

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.
