This is very similar to how I do them.  I use bigger bags in general but I also just use packing tape as its easier to deal with that a piece of rope or string.  It works well though.

Thanks for sharing!  Nice simple method without a lot of waste!
I have had many air layers that when removing I broke the roots off and ended up with a cutting to be rooted again. 
By packing the soil tight as shown here may help.  Worth a try.

So, is using the rooting compound an alternative to peeling off a section of the outer layer?
Thanks for posting.

Nice video . Thanks for sharing 

Surprised he used that much rooting hormone. I guess there is no harm in generous application of it. As Sas said, peeling the skin will make this even more effective. The video emphasized the air layer be done over the "joint", so maybe by air layering at the joint, you don't have to peel. I will experiment with and without but sure seems simpler than what I was using      

HI,
You don't need to peel, but scratching the skin will help. Just take a blade and brush against the stem. You don't have to go deep, just stay at surface level.
I did it this year.
The results were better than last year - chance or not ... for this time at least it was so.

I never use any rooting compound. You really don't need that for fig trees, except perhaps if you reallllllllllllllllllllllllllllly want to be sure to have success.
I airlayered Panaché, Osborn prolific this year and both rooted in time. I did that in mid-august, so time was running short, thus my scratchings on the stems.
I did the same for my healthy longue d'aout, but I didn't get enough roots - or any roots. I just left everything on place. I'll check by next Spring if it is rooted ...
There might have been one or two tiny roots, but for fear for breaking them, I didn't investigate further.

Thanks for posting the video. It's similar to what I do. I got the idea from my Asian friends on Facebook. It is a common method use in Asian countries.

I use a bit larger bag and zip ties. Be sure the potting soil is moist enough to be able to pack firmly so when the bag is slit the soil doesn't crumble and fall out.

On brown wood I usually remove a 1/4 by 1 inch long strip of bark. I haven't tried the rooting harmone yet.

This looks like a nice, quick, alternative method. You could make these bags in abundance ahead of time and slap them on quite a few branches in no time!
One thing that I would add. I would first secure a small bamboo stick over the branch to give it support. Then slip the soil bag over both sticks. That way, there is no risk of the fig branch bending or breaking if it is too green or too thin.

I like his method.  Honestly if you ever bought Air Propagators, its the exact same technique just super cheaper and less sturdy.

I have several of these propagators, they work very well.

I was surprised at how tightly packed the soil was.  I would have thought it would make it harder for the small roots to push through, but i guess not.  On another video he pushed cuttings into a cup with the same hard packed soil.

I wrap mine in aluminum foil to deflect heat in summer time.I will
try this method because it looks cheap and easy.
