Growing guide

What to do through the growing season

  1. 01

    Sow Seeds

    26 Apr to 24 May Optional · repeat every 3 weeks

    Sow seeds thinly where the plants are to grow, from 26th April to 24th May. Cover them with a light layer of soil, about deep, and keep the soil just moist until germination.

  2. 02

    Thin Seedlings

    10 May to 21 Jun Dates as each sowing reaches this stage

    When seedlings are large enough to handle, from 10th May to 21st June, thin them to one plant every . Keep the strongest plants and remove extras cleanly at soil level.

  3. 03

    Water New Plants

    10 May to 12 Jul Dates as each sowing reaches this stage

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

    17 May to 2 Aug 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

    21 Jun to 16 Sept Dates as each sowing reaches this stage

    Pick young leaves and open flowers from 21st June to 16th September. Harvest often, taking small amounts from several plants so they keep producing fresh growth.
