Growing guide

What to do through the growing season

  1. 01

    Sow Seeds

    14 Mar to 28 Mar

    Sow seeds thinly around 14th March - 28th March on the surface of fine seed compost, then cover with a very light dusting of compost or vermiculite. Keep the tray in a warm, bright place and just moist until germination.

  2. 02

    Prick Out Seedlings

    4 Apr to 2 May Dates as each sowing reaches this stage

    When seedlings are large enough to handle, prick them out from 4th April into small pots. Keep the strongest plants and handle them gently to avoid damaging the roots.

  3. 03

    Harden Off

    9 May to 9 Jun Dates as each sowing reaches this stage

    From 9th 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

    23 May to 9 Jun

    Set plants in their final position from 23rd May in full sun and very free-draining soil, spacing them apart. Water in thoroughly straight after planting, then allow the soil to dry out between waterings, as sage dislikes wet roots.

  5. 05

    Pinch Tips

    28 May to 26 Jul Dates as each sowing reaches this stage Optional · repeat every 4 weeks

    From 28th May, pinch out soft growing tips regularly to keep the plant bushy and to delay flowering. Stop pinching by 26th July so the plant hardens off before colder weather arrives, and never cut hard into old bare wood.

  6. 06

    Harvest Leaves

    12 Jun to 25 Aug Dates as each sowing reaches this stage Optional · repeat every 3 weeks

    Pick a few leaves from 12th June once plants are well rooted, then keep harvesting little and often through 25th August. Take tips for the best flavour and leave enough growth for the plant to keep thickening up.
