Ferns produce spores, not seed, and I don't find a lot of information on this one. Ferns in general: You must sterilize the growing medium or you will have problems of competition from algae and mosses. For all species you need to maintain reasonably high humidity. (i.e. sealing pots in plastic bags, or sowing under glass.) Don't sow the spores too thickly. Most species need good but not direct light. |
