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.
Gymnocalycium oenanthemum seeds will usually germinate in 5-180 days, even under good conditions germination may be erratic.
Sand, and loam, with some sphagnum moss or coir (coconut fiber/dust) make a good mix for germinating Gymnocalycium oenanthemum and similar seeds. The mix needs to be free-draining, and to be slightly water retentive. Surface sow the seeds and just cover with sand. Start germinating the seeds in shady (dark), humid conditions. As the seeds start to germinate, increase the light and decrease the humidity.
