I have no luck with bagging. I tried that last winter even spent money and bought heat pads and did not work. I had leaves but no roots and the ones got roots are very few and weak roots to survive a tree. I have seven fig trees and I AIRLYERED 6 branches. I followed the instruction on Google and used very small amount of rooting hormone. I used potting soil not moss and covered the plastic bag wit foil paper. It has been 5 weeks and I was itching to see what happened but controlled myself. Today I had big itch to find out and opened the foil paper it is amazing the rooting bags are full with white healthy roots. In two weeks i will pot all of it. What is really amazing is that one branch even developed lots of roots it has one little fig on it. I guess this will never ripen after the branch is separated from the mother tree.I am so exciting about air-layering I will air-layer apricot, peach , nectarine and grapes.
