Preserving Food Safely - 01600809


To obtain the maximum yield of Jerusalem artichokes,
wait until late fall when the leaves of the plant begin to
die before harvesting the tubers. Store tubers in a cool
place (32 to 40 degrees Fahrenheit) embedded in moist sand
to keep the humidity high. If the humidity is not kept
high, the tubers will shrivel.

Jerusalem artichokes may be left in the ground over
winter. Mulch heavily so that the ground doesn't totally
freeze. Dig up tubers as needed.
