Store them in a pot of dry dirt. Cut them a cpl days before planting to allow the cut to scab over. best if you can dip wet cut in wood ash so that insects dont find it attractive.

An old timer told me if you wait until after the first frost to harvest the tubers they cause much less flatulence. He said before the first frost they call them fartichokes. : ) Planting for the first time this year and will definitely apply this advice.

Yikes, I thought I could grow Sunchokes in zone 5 and bought a few. What do I do now? Can I still plant them in sunny spot or eat and wait next year? Are they still good if they got soft? I forgot them in the garage for a week. Thanks!

I just harvested the jerusalem artichoke that we planted last spring. The flowers were done but the plant was still alive. I have lots of small tubers and thick root with sprouts. Is all this OK to cook and eat?

I live in zone 8a. It gets very warm here, until late November. Can I store my Jerusalem Artichoke tubers in the refrigerator until I plant them spring?

Are Jerusalem Artichokes perinnials? Do I need to dig up and replant in spring? Zone 4a
