Orchids can be propagated from seeds or in vitro.
In the case of seed propagation, we use the same method as in vitro We add substances which replace natural for orchid fungus eg: small piece of potato, swede or banana. Alternatively coconut milk or pineapple juice can be used. It should be remembered about 2-3 days stratification of seeds. Seeds germinate very well, we can expect at least 70% of the seeds sprout.
Orchids have very tiny seeds although their abundance with one plant is enormous. For example, one Dactylorchiza plant can give several thousand seeds.
Growing plants from seeds is a long period. After a year we can replant seedlings into the permanent place. Of course stratification is required before that. Plants will blossom after 4 - 6 years.
Winter period is essential in cultivation of hardy orchids. During winter rest they save energy while they have limited access to food sources. As a result hardy orchids become much stronger and healthy
