Wasabia japonica, plants with roots
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.
Wasabia japonica seeds will usually germinate in 60-90 days, if conditions are favourable.
Outdoor Treatment, in temperate regions, can give Wasabia japonica seeds exactly the sequence of cold and damp and warm conditions needed to encourage germination. Check your weather conditions to see whether they may be appropriate. Shady sheltered conditions are recommended (to keep humidity and temperature regular) in a free draining, but water retentive medium - this can be in pots in a cold frame, where they can be easily protected from weeds and animals.
Do not let Wasabia japonica seeds dry out. Cool, damp conditions are necessary. Cold frame. Gibberellic acid. Fresh (undried) seeds germinate best at 5°C, some stored seed may germinate at 10°C.
