How to grow

Cultivation

Grow on an open, sunny site with deep, light soil. Keep the soil evenly moist to prevent roots splitting. Add well-rotted manure the previous autumn, especially if growing on a clay or chalk soil. Chalk and clay aren’t ideal for growing parsnips so you could also try deep containers. The ideal soil pH is 6.5-7 so adjust pH where necessary. See parsnip cultivation for more information.

Propagation

Propagate by seed. See sowing vegetable seeds
