They will be fine Val. You can't kill them, and they grow fast and multiply. I started with three small corms (2cm across), about 4 years ago. I now have a patch about 3 metres square.

I saw some jerusalem artichokes in Woolies, and bought them intending to plant, but I see that it is in our warm weather you advise, if I plant them now in July will they just rot in the ground. If so how can I store them as they hardly ever appear in the stores

Mine live in the soil all winter. Its a raised bed with good drainage though. I usually collect the ones I need throughout the dormant period and leave the rest. Manure in spring and away you go.

I wondered the same thing about two months ago when I got some. I saw it starting to dry out so planted in pot with top showing to observe. Root never looked back and with sun on it is clearly photosynthesizing and just waiting for warmer weather to burst forth.

Just pot them up into a pot with some good potting mix and compost, keep moist but not wet. Pot them out when they sprout. I leave them in the ground here, the dont usually rot over winter.

I've just harvested 4 kg from 3 small plants I brought home from my folks in SEQld at xmas. Couldn't leave them in the ground as they were beginning to soften - would have led to rot int he coming wet season . Well drained soil but too wet and warm here to winter them in ground. Now I am looking for alternative storage methods. Does anyone know if you can parboil and freeze 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.
