Growing guide

What to do through the growing season

Change the guide to see different planting timelines and tips.

Best for gardeners starting a few plants at home in pots or a seed bed. It is slow from seed, so expect light picking in the first year and fuller harvests after that.

  1. 01

    Sow Seeds

    25 Mar to 25 Apr

    Sow seeds thinly on the surface of seed compost from 25th March to 25th April and press them in gently. Do not cover them deeply, as they need light to germinate.

  2. 02

    Thin or Prick Out Seedlings

    15 Apr to 30 May

    When seedlings are large enough to handle, from 15th April to 30th May, thin them or prick them out into small pots. Keep them just moist and give plenty of light so they do not become leggy.

  3. 03

    Harden Off

    16 May to 30 May

    From 16th May to 30th May, acclimatise plants to outdoor conditions over about 10 days. Put them out for longer each day, and protect them from cold nights and strong wind.

  4. 04

    Plant Out

    30 May to 23 Jun

    Move plants to their final position from 30th May to 23rd June, once the soil has warmed and all frost risk has passed. Space them apart, plant at the same depth as in the pot, and water them in thoroughly straight away.

  5. 05

    Pinch and Water

    13 Jun to 9 Oct Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    From 13th June to 9th October, pinch out the tips regularly to keep plants compact and bushy. Water sparingly once established, only when the compost or soil has dried a little, as oregano dislikes sitting wet.

  6. 06

    Harvest Leaves

    17 Jun to 9 Oct Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    Pick lightly from 17th June to 9th October once plants are well rooted and growing strongly. Snip shoot tips rather than cutting into old bare stems.
