Growing guide

Step-by-step instructions for growing Kale

  1. 01

    Sow Seed

    23 Mar to 21 Jun every 3 weeks

    Sow seeds around 23rd March - 21st June in a prepared seedbed or shallow drills. Sow thinly to a depth of and keep the soil evenly moist while they germinate.

  2. 02

    Thin Seedlings

    12 Apr to 2 May

    When seedlings are large enough to handle, thin them out so the strongest plants have room to develop. Keep the bed watered, and protect the young plants from pigeons if they are taking a liking to the leaves.

  3. 03

    Transplant and Firm In

    21 May to 4 Jun

    Move plants to their final position when they are sturdy enough to handle. Space them about apart, then firm the soil hard around each plant so the roots are anchored well and wind-rock is avoided. Water in thoroughly straight after planting.

  4. 04

    Protect from Pests

    28 May to 28 May

    Fit fine netting over the row from 28th May to keep out cabbage white butterflies and pigeons. Add brassica collars round the stems to help prevent cabbage root fly from laying eggs at the base.

  5. 05

    Feed Regularly

    11 Jun to 24 Nov every 4 weeks

    Start feeding once the plants are properly settled, then repeat every 28 days through the main growing period. Use a nitrogen-rich feed and keep the soil moist so the leaves stay tender and keep coming.

  6. 06

    Harvest Leaves

    11 Aug to 24 Nov

    Start picking from 11th August once the plants are well established. Take the outer leaves first and leave the growing point intact so the plant keeps cropping. Regular picking keeps the plants productive right through to 24th November.

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.
