Plant seeds 5mm-1 cm deep in loose rich compost and cover with row cover or low tunnel to increase germination time. Soil should be 10-25 C and be kept moist during the germinations period of 14-21 days. The ground should be prepared similar to carrots, the looser the soil the better the parsnips will grow. Generally, only 60% of parsnip seeds will germinate so plant seeds 2 cm apart and thin to 12-20 cm apart.
Harvest after frost for best flavour. We cover ours with 20 cm of straw and then cover with a low tunnel. By lifting the tunnel and the mulch we harvest our parsnips all winter as needed.
We grow in a high raised beds, 60-80 cm, for easy harvesting.
