Growing guide

What to do through the growing season

  1. 01

    Sow Seeds

    27 Mar to 24 Apr Optional · repeat every 3 weeks

    Sow seeds thinly where the plants are to grow, from 27th March to 24th April. Cover them with a light layer of soil, about deep, and keep the soil just moist until germination.

  2. 02

    Thin Seedlings

    10 Apr to 22 May Dates as each sowing reaches this stage

    When seedlings are large enough to handle, from 10th April to 22nd May, thin them to one plant every . Keep the strongest plants and remove extras cleanly at soil level.

  3. 03

    Water New Plants

    10 Apr to 12 Jun Dates as each sowing reaches this stage

    Water plants in well after thinning, then keep the soil lightly moist through 10th April - 12th June 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 Out Flower Buds

    17 Apr to 3 Jul Dates as each sowing reaches this stage

    If you are growing borage mainly for leaves, pinch out the first flower buds as they appear. This keeps plants producing fresh leaves for longer. If you want flowers, leave the buds to open.

  5. 05

    Harvest Leaves And Flowers

    22 May to 12 Oct Dates as each sowing reaches this stage

    Pick young leaves and open flowers from 22nd May to 12th October. Harvest often, taking small amounts from several plants so they keep producing fresh growth.
