When I have TOO many orchid seed pods, I will sprinkle them on mounts or in the pots, or in conditions in which I think they will germinate naturally. Terrestrial orchid species are MUCH easier than the epiphytes and lithophytes. Otherwise, the seed pods will typically be flasked.
The idea of sprinkling seeds around the base of the mother plant basically suggests that if the mother plant germinated from that spot, then more can germinate from there. It was a lack of understanding how orchid seeds germinate and what fungi and conditions they need in order to germinate (1800's to early 1900's). With sprinkling seeds, it's hit and miss. With flasking, it is usually more efficient in germination...
