Sowing it outdoors
- Pull out any weeds and rake the top of your bed until it's crumbly, like cake crumbs
- Make a little line in the soil (1cm deep) with your finger or a stick
- Drop the seeds in, about 45cm apart each way
- Gently cover them with soil and pat it down
- Water with a watering can that has a sprinkler head
- Push in a label so you remember what's there
Top tips for growing borage
- It gets big and floppy - give it room at the end of a bed.
- It seeds itself everywhere, so pull out the ones you don't want.
Soil and feeding
Poor soil - really!. Nasturtiums flower best in poor soil. Feed them and you get all leaves and no flowers.
Harvesting and eating borage
Pick the blue flowers when they're fully open.
How to eat them: Freeze the flowers in ice cubes - they look amazing in a drink. They taste a bit like cucumber.

Saving your own borage seed
Late summer and autumn, as the flowers fade.
- Stop deadheading a few flowers - let them fade on the plant
- When the seed heads are dry and brown (and the seeds rattle), snip them off on a dry day
- Shake the seeds into a paper bag
- Spread on a plate to dry for a week
