Luck is another component.
quality of the cutting is also another component.
I send cuttings all over the country and even to my fig friend in Brazil, and they root and grow at much better rate than mine.
I grow lots of plants with success. figs are tricky to me. All my rooting methods combined amount to 90% mortality. I am a failure at it. I also tried all methods. what seems to work is hot weather and neglect. Shove them in the soil, cover with a bottomless with lid cracked open, so very hot air can scape, put it in some filtered sunlight (under another plant) so, it does not 'cook' the cutting. Forget about it.. and you will see growth.
it can be very frustrating... there are also those enemies: Gnats. Almost invisible larvae that seems to find their way in the most tied spaces.
I wish you luck... just don't give up...
