Growing notes

Light

Needs an open site in full sun.

Soil

Deep, light, well-drained soil without stones, pH 6–7. Do not dig in compost or manure just before sowing; stones, compaction and fresh organic matter make the roots fork.

Care

Sow fresh seed 1 cm deep where the plants are to grow — parsnips do not transplant well. Seedlings take two to three weeks to come up, so keep the soil surface moist until then. Water about 25 mm a week in dry weather and keep the moisture even, or the roots may split. Lift the roots after the first hard frost; they can stay in the ground over winter but should be dug before new leaves grow in spring. The sap can irritate skin in sunlight, so wear gloves and long sleeves when handling the leaves.
