it just wanted to practice the air layering process.
plus i started the air layering before i started the other cuttings

Its definitely worth trying. I would have thought that you'd get a  much quicker response, as the tree is still 'living.'  I dont know if there is any advantage to this method.

Once you get a tree fairly established, maybe you could keep at it and do some more controlled experiments.  Could even try a little rooting hormone to possibly jump start it.

Have you identified the tree/figs yet?

i did try hormones on one of the layerings and it was the one that rooted first. i didn't find out which tree it is because the birds keep eating the fruit before i get to them.

the only advantage i can think of is that you will start with a all ready established plant with what ever was on the tree. other than that idk
