how to save Jerusalem artichoke to grow next year

we have some Jerusalem artichokes on our allotment, how do we go about saving some to move to another plot next year ?

They won't be ready to dig before the tops start dying off, possibly about late Oct early Nov. When you dig them select the ones you want to plant in the new plot and bung 'em in a pot or straight where you want them to grow. You can't lift them to store for later it just doesn't work.

Absolutely easy, like weed. Theoretically. In practice, after the last 5 years of failure on my new plot, I'd advise to plant some in pots for spring planting, if autumn sown are eaten.
