You can start to grow Libertia in either spring or autumn.
It is perhaps simplest in the spring. The seeds should be sown about 3 mm (1/8th inch) deep into flats. Then the seeds should be imbibed by placing the flats in a black plastic bin bag. Next, place in the fridge for three weeks.
After this chilling, sink the flats outdoors in the shade and cover with glass.
As soon as seedlings appear (germination takes from one to six months), transplant them at about 50 cm (20 inches) apart into a sunny part of the garden.
The location should have good drainage. Ideally the soil should be both moist and sandy.
Although Libertia likes to grow in sunny areas, it should not be in an open area as the plant needs to be protected from strong winds.
If you require more Libertia, then they can be divided in the spring time.
