Propagation Method
Seed Information
Seed Collection
Collect spores when mature on the frond. Unripe sori are generally light green then change to yellowish-brown and to dark brown or black when mature. Place fronds, or portions of fronds, containing ripe spores in a paper bag and leave in a dry and draught-free place. Spores should begin to release immediately and all spores are released within days unless the species has tough, leathery fronds. Some species produce large quantities of spores from one frond, others require many fronds to produce similar quantities.
Cutting & Division Information
Propagate by division.
