Grow loose-leaf lettuce varieties for repeated harvesting of outer leaves over a long season.

  1. 01

    Sow Seeds Outdoors

    12 Apr to 10 Sept Optional · repeat every 2 weeks

    Sow a short row from 12th April - 10th September. Sow deep, water gently, and repeat every 14 days. Germination stalls in hot soil, so keep the seedbed cool and moist.

    • In midsummer, a little light shade helps stop plants bolting.
  2. 02

    Thin Seedlings

    26 Apr to 1 Oct Dates as each sowing reaches this stage

    Thin seedlings to apart once they have their first true leaves, around 26th April - 1st October. Snip the extras at soil level and eat them.

  3. 03

    Protect from Pests

    3 May to 25 Oct Dates as each sowing reaches this stage

    From 3rd May, protect plants from slugs and snails. Check regularly, especially after rain, and keep this up through 25th October.

  4. 04

    Water Consistently

    26 Apr to 25 Oct Dates as each sowing reaches this stage

    From 26th April, keep the soil evenly moist. Dry soil makes lettuce bolt. Water at the base, and keep this up through 25th October.

  5. 05

    Harvest Outer Leaves

    17 May to 25 Oct Dates as each sowing reaches this stage

    Start picking outer leaves around 17th May once they are large enough to eat. Cut them near the base and leave the centre so the plant keeps growing. You can keep cutting through 17th May - 25th October.

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.
