Growing orchids from seed is a fairly specialised task and it requires a bit of knowledge of tissue culture techniques. I suggest that anyone wishing to try this should first contact their local Orchid Society, or purchase a book on the subject, or both! Orchid seeds should only be bought by experienced orchid growers or dedicated gardeners that are willing to devote a lot of time to research orchids grown from seed and to the long time and a lot of labour that this method of Orchid propogation requires.
