Growing guide

Step-by-step instructions for growing Nigella

  1. 01

    Sow Seeds

    10 Apr to 5 Jun every 3 weeks

    Sow thinly around 10th April - 5th 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

    22 May to 5 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

    7 Jun to 28 Sept

    From 7th 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

    7 Jul to 28 Sept

    Start picking and deadheading from 7th 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

    6 Aug to 28 Sept

    Collect ripe seed heads from 6th August once they have dried and turned papery. Hang them indoors to finish drying, then shake out the seed for sowing next year.
