I have tree but I don’t think it pollinates due to a lack of a specialized wasp that pollinates it. I think the primary means of propagation where the wasp isn’t present is air layer. Could be wrong tho.
might try using carica pollen. so far only 3 species have been crossed with carica...
ficus auriulata - subgenus: sycomorus / section: sycomorus / subsection: seomorphe
ficus erecta - subgenus: ficus / section: ficus / subsection: frutescentiae
ficus pumila - subgenus: synoecia / section: rhizocladus / subsection: plagiostigma
dammaropsis is in the same subgenus as auriculata, but in a different section, "dammaropsis". if it worked then maybe the result would be a giant and tasty fig fruit.
