Growing guide

Step-by-step instructions for growing Nigella

  1. 01

    Sow Seeds

    14 Apr to 9 Jun every 3 weeks

    Sow thinly around 14th April - 9th June on finely raked, weed-free soil. Cover with a light depth of , then keep the seedbed just moist until seedlings appear. Sow a fresh batch every 21 days if you want a longer run of flowers.

  2. 02

    Thin Seedlings

    26 May to 9 Jun

    When seedlings are large enough to handle, thin them to apart. Do it gently, because crowded plants make fewer flowers and weak stems.

  3. 03

    Feed and Water

    11 Jun to 11 Oct

    From 11th June, water only in dry spells and avoid overfeeding, which gives soft growth and fewer blooms. A light mulch helps the soil hold moisture without making the plants lush.

  4. 04

    Deadhead Flowers

    11 Jul to 11 Oct

    Start picking and deadheading from 11th July to keep the plants flowering for longer. Cut stems regularly for the vase, and leave a few seed heads if you want self-seeding.

  5. 05

    Harvest Seed Heads

    10 Aug to 11 Oct

    Collect ripe seed heads from 10th August once they have dried and turned papery. Hang them indoors to finish drying, then shake out the seed for sowing next year.
