Seed Raising Advice

Sow seeds at any time, covering them with compost or grit 5mm deep.Keep the seed pot in a cool, well-lit spot outside. Artificial heat is not needed and will prevent germination so be very patient as many species will only germinate in the spring after chilling or freezing of the moist seed tray in winter. Grow on individual seedlings in small pots until they are of  sufficient size to be potted on or planted out into the open ground.
