@"TorontoJoe"#1 technically with cauliflorous ficus trees the figs don't grow directly on the trunk. the figs grow on "branchlets" that grow on the trunk, as you can clearly see in
this very relaxing 3 minute video of ficus auriculata. it took some digging to find the word "branchlet".
i think that
ficus semicordata has the longest branchlets. in
this video you can see a ficus auriculata with relatively long branchlets. the jelly fig and ficus racemosa have relatively short branchlets.
typically, the branchlets begin to form low on the trunk near the ground. as the tree grows larger the branchlets develop higher and higher up the trunk.
so air-layering cauliflorous ficus trees typically doesn't produce a tree that quickly develops figs, unlike with carica. my big question is whether it's possible to remove a branchlet or snippet of a branchlet and graft it onto the trunk of an immature tree. this will be my #1 grafting experiment to try in the spring.
@"GoodFriendMike"#9 look how nicely i'm concentrating on the branchlets.
