|I have ordered bismarck nobilis seeds from the States.
My question is: What you must do too let them germinate?
|Sow fresh seeds in a sandy, peaty soil; keep at a temperature of 75 to 85F. They have a special requirement: they must be sown in containers that are at least 2 feet deep. Some people use up-ended drain pipes.
Upon germination the seed sends downa long, rootlike structure; the plant then develops from this structure. The seeds should germinate in 4 to 6 weeks.
