Q.Will This Year’s Tuberless Jerusalem Artichokes Plant Regrow Next Year If Top Cut Off?.
I ordered in February for early May planting jerusalem artichokes. The seed company delayed delivery instill June for Vt. Therefore no tubers grew 110 days. I know someone grows them 12 miles from my home. Will they regrow without tubers? By cutting tops and leaving this year’s roots in the garden?

Cut away any dead foliage, but leave the roots undisturbed. They should continue to grow next spring. They are hardy in zones 3-9. I suggest mulching well after the first frost.
