Borago officinalis
A fast-growing annual herb with edible flowers and cucumber-flavoured leaves. It grows well in most UK gardens, self-seeds freely, and is best sown direct where it is to flower.
Step-by-step instructions for growing Borage
Sow seeds thinly where the plants are to grow, from 27th March to 22nd May. Cover with a light seed dressing of and keep the soil just moist until germination.
When seedlings are large enough to handle, from 8th May to 22nd May, thin them to one plant every . Keep the strongest plants and remove extras cleanly at soil level.
Water plants in well after thinning, then keep the soil lightly moist through 8th May - 12th June while they establish. Once rooted, borage copes with moderate dryness, but flowers are better if the soil does not dry out completely.
From 15th May to 3rd July, pinch out the tips regularly while plants are young. That makes them bushier and delays flowering, which gives you more leafy growth for longer.
Pick young leaves and open flowers from 19th June to 1st October. Harvest often, taking small amounts from several plants so they keep producing fresh growth.
Tap a plant to see why it works (or doesn't) with Borage.
Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
