Extract the seeds from their pods. They should fall out easily. Sow them straight away.
When you have sown the seeds, cover the compost with sharp grit.
When seedlings have strong shoots and roots, knock them out of the tray and separate.
Pot up seedlings individually into modules or small pots.
Finish the surface of each pot with grit to retain moisture, keep down weeds and provide drainage around the crown of the plant.
