Growing guide

What to do through the growing season

  1. 01

    Sow Seeds

    12 Mar to 26 Mar

    Sow thinly around 12th March - 26th March on fine seed compost. Cover with a light dusting of compost or vermiculite. Keep the tray warm, bright, and just moist until it germinates.

    • A bought plant is quicker. Softwood cuttings are another route.
  2. 02

    Prick Out Seedlings

    2 Apr to 30 Apr Dates as each sowing reaches this stage

    When seedlings are large enough to handle, prick them out from 2nd April into small pots. Keep the strongest plants and handle them gently to avoid damaging the roots.

  3. 03

    Harden Off

    7 May to 7 Jun Dates as each sowing reaches this stage

    From 7th May, move plants outside for a few hours each day over about 10 days. Keep them sheltered and bring them in if cold nights are forecast.

  4. 04

    Plant Out

    21 May to 7 Jun

    Set plants in their final spot from 21st May in full sun and free-draining soil. Space apart. Water in, then let the soil dry between waterings.

    • In a pot, stand it in a rain-shadow in winter. Pots stay wet in winter rain and that is how they rot.
  5. 05

    Pinch Tips

    26 May to 24 Jul Dates as each sowing reaches this stage

    From 26th May to 24th July, pinch out soft growing tips to keep the plant bushy. This is a first-year pinch, not a yearly prune. Never cut into old bare wood.

    • On established plants, prune lightly in mid to late spring. Never into old wood.
  6. 06

    First Harvest

    10 Jun to 23 Aug Dates as each sowing reaches this stage

    Pick a few leaves from 10th June once the plant is well rooted. Take tips for the best flavour. Leave enough growth for the plant to thicken. Keep this light pick through 23rd August.

    • Once established, you can pick all year. Flavour is best on spring and summer growth.
