Parsnips - Illinois Vegetable Garden Guide - University of Illinois Extension



Parsnips are grown like other root crops, such as carrots and beets, except that parsnips require a longer growing season, and ridging to keep soil over their shoulders.

You can dig up the roots late in the fall or leave them in the ground, since winter freezing will not hurt them. The roots are 10 to 12 inches long, so be careful when digging them up.
