Growing guide

What to do through the growing season

  1. 01

    Prepare the Bed

    5 Apr to 26 Apr

    Work the soil deeply and break it down to a fine tilth around 5th April - 26th April. Remove stones and any hard lumps, then mix in well-rotted compost. Avoid fresh manure, because it makes the roots fork.

  2. 02

    Sow Seeds Indoors

    17 Feb to 8 Mar

    Sow seeds thinly on the surface of moist seed compost around 17th February - 8th March and cover with a light dusting of vermiculite. Keep them at in bright light and keep the compost evenly moist.

  3. 03

    Prick Out Seedlings

    10 Mar to 12 Apr Dates as each sowing reaches this stage

    When seedlings are large enough to handle, prick them out from 10th March - 12th April into individual small pots or modules. Handle them by the leaves and keep the young plants in bright light with evenly moist compost.

  4. 04

    Harden Off and Plant Out

    3 May to 17 May

    Harden plants off for 7 to 10 days, then plant out around 3rd May - 17th May after frost risk has passed. Space plants apart with the crown at soil level. Water in thoroughly and keep the soil evenly moist.

  5. 05

    Harvest Roots

    8 Sept to 29 Nov Dates as each sowing reaches this stage

    Lift roots from 8th September and keep harvesting through 29th November. Leave sound roots in the ground over winter if the soil drains well, then lift them as needed before they start to run down.
