Growing guide

What to do through the growing season

  1. 01

    Sow Seeds

    28 Mar to 11 Apr Optional · repeat every 3 weeks

    Sow seeds thinly on the surface of moist seed compost around 28th March - 11th April. Cover very lightly with compost, because parsley germinates slowly and unevenly. Keep the compost evenly moist while you wait for shoots to appear.

  2. 02

    Thin Seedlings

    18 Apr to 9 May Dates as each sowing reaches this stage

    When seedlings are large enough to handle, from 18th April, thin them so the strongest plants have space to develop. If several have been sown close together, lift extras carefully rather than disturbing the roots too much.

  3. 03

    Pot On

    25 Apr to 16 May Dates as each sowing reaches this stage

    Move each plant into its own small pot from 25th April once roots have filled the module or seed tray. Handle the seedlings gently and keep them in bright light so they do not stretch.

  4. 04

    Harden Off

    16 May to 23 May

    Harden plants off from 16th May to 23rd May. Put them outside for a few hours a day at first, bring them back in at night, then increase the time outside so they are ready to plant out.

  5. 05

    Plant Out

    23 May to 6 Jun

    Set plants in their final position from 23rd May, spacing them apart in moist, well-drained soil. Water them in thoroughly straight after planting, then keep the soil evenly moist while they settle.

  6. 06

    Remove Flower Stalks

    22 Jun to 23 Nov Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    From 22nd June, check plants every 14 days and remove any flower stalks as soon as they appear. Flowering makes the leaves tougher and bitter, so cutting the stalks away keeps plants productive. Keep picking outer leaves to encourage new growth.

  7. 07

    Harvest Leaves

    27 Jun to 23 Nov Dates as each sowing reaches this stage Optional · repeat every week

    Start picking from 27th June when plants are well established, then cut outer stems as needed through to 23rd November. Take leaves little and often, and never strip a plant bare so it can keep producing.
