Uses less space. Thin out to only 7cm (3in). Far and away the most resistant variety to canker.
For long parsnips you need a deeply dug soil which has been manured for a previous crop. However, they will do well on ordinary well drained and cultivated soil. Sow April to June, 1cm (½ inch) deep in drills 30cm (12 inches) apart. Sow clusters of 4 seeds every 20cm (8 inches) and thin out to the strongest seedlings after germination. Germination is very slow and it is helpful to sow a pinch of lettuce seeds between each cluster of seeds. They will mark the row and can be cut before the parsnips need the room.
Parsnips are a good source of energy boosting carbohydrates and are high in Vitamin C and potassium.
