Growing guide

Step-by-step instructions for growing Parsley

  1. 01

    Sow Seeds

    11 Feb to 27 Jun every 3 weeks

    Sow seeds thinly on the surface of moist seed compost around 11th February - 27th June. 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

    4 May to 18 May

    When seedlings are large enough to handle, from 4th May, 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

    11 May to 25 May

    Move each plant into its own small pot from 11th May 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

    30 Mar to 13 Apr

    From 30th March, put plants outside for a few hours a day and bring them back in at night. Build this up over about 10 days so they adjust before planting out.

  5. 05

    Plant Out

    27 Apr to 25 May

    Set plants in their final position from 27th April, 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

    Pinch Out Tips

    10 Jun to 24 Dec every 2 weeks

    From 10th June, pinch off the growing tips regularly to stop plants becoming leggy and to encourage fresh leafy growth. Remove any flower stalks as soon as they appear, because flowering makes the leaves tougher and less useful.

  7. 07

    Harvest Leaves

    6 Jul to 24 Dec every week

    Start picking from 6th July when plants are well established, then cut outer stems as needed through to 24th December. Take leaves little and often, and never strip a plant bare so it can keep producing.

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.
