When & How to Harvest Parsnips
Parsnips need a long season, and harvest timing affects both size and eating quality. Roots are usually best after cool fall weather, when they have fully sized up.
How to tell it is ready
Harvest when roots are well developed, often 1 to 2 inches across at the crown and long enough for the variety. Shoulders may show slightly above the soil, and the foliage often begins to fade as the season ends.
How to harvest
Use a digging fork to loosen the soil deeply beside the row, then lift roots carefully. Pulling without loosening the soil can snap the long roots.
Timing
Parsnips often need about 100 to 130 days to mature. Most gardeners harvest in late fall after several cool nights, and roots can sometimes remain in the ground into winter where soil does not freeze hard. Dig in stages if needed.
After the harvest
Cut off the tops and brush away loose soil after digging. Keep roots cool and humid for storage, and avoid washing until use unless necessary. Handle gently so roots do not bruise or break.
Tips
Mark the row well, since parsnips stay in the ground a long time. Do not rush harvest before roots have had time to fully size up.
