Growing guide

Step-by-step instructions for growing Borage

  1. 01

    Sow Seeds

    28 Apr to 23 Jun every 3 weeks

    Sow seeds thinly where the plants are to grow, from 28th April to 23rd June. Cover with a light seed dressing of and keep the soil just moist until germination.

  2. 02

    Thin Seedlings

    9 Jun to 23 Jun

    When seedlings are large enough to handle, from 9th June to 23rd June, thin them to one plant every . Keep the strongest plants and remove extras cleanly at soil level.

  3. 03

    Water New Plants

    9 Jun to 14 Jul

    Water plants in well after thinning, then keep the soil lightly moist through 9th June - 14th 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

    16 Jun to 4 Aug

    From 16th June to 4th 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

    21 Jul to 17 Sept

    Pick young leaves and open flowers from 21st July to 17th September. Harvest often, taking small amounts from several plants so they keep producing fresh growth.
