Growing guide

Step-by-step instructions for growing Borage

  1. 01

    Sow Seeds

    1 May to 26 Jun every 3 weeks

    Sow seeds thinly where the plants are to grow, from 1st May to 26th June. Cover with a light seed dressing of and keep the soil just moist until germination.

  2. 02

    Thin Seedlings

    12 Jun to 26 Jun

    When seedlings are large enough to handle, from 12th June to 26th June, thin them to one plant every . Keep the strongest plants and remove extras cleanly at soil level.

  3. 03

    Water New Plants

    12 Jun to 17 Jul

    Water plants in well after thinning, then keep the soil lightly moist through 12th June - 17th July while they establish. Once rooted, borage copes with moderate dryness, but flowers are better if the soil does not dry out completely.

  4. 04

    Pinch Growing Tips

    19 Jun to 7 Aug

    From 19th June to 7th August, pinch out the tips regularly while plants are young. That makes them bushier and delays flowering, which gives you more leafy growth for longer.

  5. 05

    Harvest Leaves And Flowers

    24 Jul to 7 Sept

    Pick young leaves and open flowers from 24th July to 7th September. Harvest often, taking small amounts from several plants so they keep producing fresh growth.
