Growing guide

What to do through the growing season

  1. 01

    Sow Small Batches

    28 Mar to 25 Aug Optional · repeat every 2 weeks

    Sow a short row from 28th March - 25th August. Sow another small batch every 14 days. Sow thinly about deep, in rows about apart. Keep the soil lightly moist until it germinates. In warm weather give the row a little light shade.

    • Fleece or a cloche helps if the soil is still cold.
  2. 02

    Thin Seedlings

    11 Apr to 22 Sept Dates as each sowing reaches this stage

    After each sowing, once seedlings are large enough to handle, thin to apart. Use scissors if the roots are tangled. Water the row after thinning.

  3. 03

    Check for Slugs

    9 Apr to 9 Oct Dates as each sowing reaches this stage

    From 9th April, watch young plants for slugs, snails, and birds. Hand-pick slugs or use a barrier. They can strip a row in one night, especially in damp weather.

    • If the bed is overcrowded or stays humid, watch for downy mildew on the leaves. Thin so air can move through.
  4. 04

    Keep Well Watered

    11 Apr to 9 Oct Dates as each sowing reaches this stage

    From 11th April through 9th October, keep the soil evenly moist so the plants stay tender and do not bolt. Water at the base in dry spells. In warm weather a little light shade helps. Give pots extra water; they dry out fast.

  5. 05

    Harvest Leaves

    2 May to 9 Oct Dates as each sowing reaches this stage

    Start picking from 2nd May and keep going until 9th October. Take outer leaves, or cut just above the crown for one larger crop.

    • A cloche can keep plants picking later.
