Growing Tips
Use only fresh seed each year; parsnip seed viability drops dramatically after one season (often below 50%).
Leave parsnips in the ground through winter and harvest in early spring for the sweetest flavor; mulch to prevent the ground from freezing solid.
Avoid rocky or compacted soils, which cause forked and misshapen roots; deep, stone-free beds produce the straightest taproots.
