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.
Corydalis cava seeds will usually germinate in 30-60 days, even under good conditions germination may be erratic.
Outdoor Treatment, in temperate regions, can give Corydalis cava 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.
A couple of months warm stratification at about 20°C, followed by a couple of months at 0°C, then slowly raise the temperature - germination should start at about 4°C. GA-3 is also suggested.
