Growing guide

What to do through the growing season

Dates for your town

Set your town to see planting windows worked out from local frost history, not a generic UK calendar.

  1. 01

    Prepare the Bed

    mid-April to early May UK average · set your town for your exact dates

    Work the soil deeply and break it down to a fine tilth around mid-April to early May. 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

    early March to late March UK average · set your town for your exact dates

    Sow seeds thinly on the surface of moist seed compost around early March to late 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

    late March to late April UK average · set your town for your exact dates Dates as each sowing reaches this stage

    When seedlings are large enough to handle, prick them out from late March to late 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

    mid-May to late May UK average · set your town for your exact dates

    Harden plants off for 7 to 10 days, then plant out around mid-May to late 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

    late September to mid-December UK average · set your town for your exact dates Dates as each sowing reaches this stage

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