There are several techniques for the propagation of hardy orchids.

Division of clumps: Cypripedium, Bletilla, Calanthe and Cymbidium all will form lumps if they are lucky. classes should be carefully dug out to avoid damage to very fragile fleshy roots. New plantlets can be teased apart or cut apart with a knife. Rhizome (if it is produced) can be cut with a knife as long as there is at least one healthy bud per cutting. The division should take place in early summer to allow time for the division to recover from the division process before winter. Fall divisions are possible if the plantlets overwinter indoors. Orchids may be propagated using shoot tip meristems placed in tissue culture.

Planting backbulbs: Orchid backbulbs are dormant buds that will become active when separated from pseudobulb and crew. Backbulb propagation works best for Aplectrum, Bletilla, Calanthe, Cymbidium, Calopogon and Tipularia.

for testing the germination of seeds: Orchid seeds are very difficult to grow. Most seeds no endosperm and seedlings do not make the most of the cotyledons. In the wild, they require a specific symbiotic mycorrhizae fungi provide sugars, hormones and other growth factors on the seedling until it is large enough to survive on their own. We can grow orchids seeds without fungi (asymbiotically) in sterile tissue culture lab today, thanks to a specialized process developed by Dr. Lewis Knudson of Cornell University in 1922.

seed pods need to mature for several months until they mature. pods should be surface sterilized in bleach and then a flaming alcohol. Immature pods (and seeds) are preferred because they are mature seeds are dormant and contain germination inhibitors, which require a cold period to overcome. pods are cut with a sterile scalpel, and turning to dust, like seeds. Seeds were surface sterilized and placed in special jars growth agar mixture, sugar, hormones and nutrients (so-called Knudsen formula ).

Hardy orchid seeds require dark to germinate, but when they moved germinated under the lights. After 3 months were re-plated in the flasks with fresh nutrient mix. They remain in the flasks to a year, and then be potted up. pots were grown with precise conditions of temperature, light, moisture, water and fertilizer. Some plants require a cold period in order to stimulate pseudobulb shaped. It will be at least a year before they can be transplanted into the garden. They will not flower for several years thereafter. There are commercial laboratories that will sell you supplies or will germinate your seeds for you and email you the cost of seedlings. You can buy seeds and continue to 'flasked' in tissue culture medium and wean them yourself or you can send potted plants. Now you understand why Hardy orchids can be so expensive! Bletilla seed is no exception. It will germinate in a pot, because it has a small amount of endosperm and cotyledon appears. Hardy orchids will re-seed around the garden if you happy and seedlings can be transplanted if you are careful not to damage the roots.
