Parsnips in Petton

Pastinaca sativa

Parsnip
Parsnip · Pastinaca sativa

Parsnips need a deep, stone-free soil and do best where the bed has been well dug but not freshly manured. Sow direct, keep the seedbed moist while they germinate, and use fine mesh to keep carrot fly off the row. Roots swell slowly, then can be lifted as needed through the colder part of the year.

Growing guide

Step-by-step instructions for growing Parsnip

  1. 01

    Prepare the Bed

    3 Mar to 12 May

    Dig the soil deeply and rake it to a fine tilth around 3rd March - 12th May. Remove stones and clods, and do not add fresh manure, because it can make the roots fork.

  2. 02

    Sow Seeds

    3 Mar to 29 May

    Sow seeds thinly in shallow drills around 3rd March - 29th May and cover them with fine soil. Water the row gently after sowing and keep the surface evenly moist while they germinate, as parsnips can be slow to emerge.

  3. 03

    Protect from Carrot Fly

    15 Apr to 13 May

    Put fine insect-proof mesh over the row from 15th April straight after sowing and seal the edges well. Leave it in place as the seedlings come through, because carrot fly can find exposed rows very quickly.

  4. 04

    Thin Seedlings

    20 May to 30 May

    Thin seedlings from 20th May - 30th May once they are large enough to handle, leaving the strongest plants at apart. Do it on a damp day if you can, then water the row afterwards so the roots settle cleanly.

  5. 05

    Harvest Roots

    13 Aug to 6 Mar

    Lift roots from 13th August once they have reached a usable size, and carry on through 6th March. Later roots are sweeter after cold weather, and many can stay in the ground if the soil drains freely and is not waterlogged.

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
