  1. 01

    Sow Seeds Indoors

    16 Mar to 30 Mar

    Sow seeds in modules or trays from 16th March - 30th March. Cover lightly with of compost and keep at for germination. Provide bright light to prevent leggy seedlings.

  2. 02

    Prick Out Seedlings

    6 Apr to 13 Apr

    Prick out seedlings into individual pots when they have two true leaves, around 6th April - 13th April. Handle them by the leaves to avoid damaging the stems. Grow them on in a cool, bright spot.

  3. 03

    Harden Off Plants

    20 Apr to 27 Apr

    Harden off plants over 7-10 days before transplanting, from 20th April - 27th April. Gradually expose them to outdoor conditions by placing them outside during the day and bringing them in at night.

  4. 04

    Transplant Outdoors

    27 Apr to 11 May

    Transplant seedlings outdoors from 27th April - 11th May. Space them apart in well-drained soil. Water in well and protect from slugs with organic deterrents.

  5. 05

    Water and Feed

    18 May to 30 Oct every 2 weeks

    Water regularly to keep soil moist and apply a balanced liquid feed every two weeks from 18th May - 30th October. Consistent moisture prevents bolting and encourages firm heart formation.

  6. 06

    Harvest Whole Heads

    23 Jun to 30 Oct

    Harvest heads when they feel firm and full, from 23rd June - 30th October. Cut the entire head at the base with a sharp knife. Harvest in the morning for the crispest leaves.

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.
