How do I store parsnips?
Harvest parsnips in mid- to late November as cool fall temperatures convert starch to sugar and give parsnips their distinctive flavor. After harvest, trim the foliage back to within 1 inch of the roots. Store parsnips at a temperature of 32 degrees Fahrenheit and a relative humidity of 95 to 98 percent. Small quantities can be placed in perforated plastic bags and stored in a refrigerator. A basement storage room or root cellar are suitable storage sites for large quantities.
