Some knowledge about growing from seed is necessary to germinate even the easiest seeds.
Most seeds require humidity to germinate, even desert plants like
require that their growing medium remains moist until germination.|
Most seeds require oxygen to germinate, if buried too deep in their growing medium, or if the medium is too wet,
the seeds may not get the oxygen they require.
Xanthorrhoea australis seeds will usually germinate in 30-180 days, even under good conditions germination may be erratic.
Sow Xanthorrhoea australis seeds on the surface of a firmly tamped down peat compost, the spores must be kept warm and damp at all times, and need daylight.
