Best way to air-layer a fruit tree?

[Weboh]

I've seen several guides for how to do this online. However, they still leave me with questions:

• I haven't been able to find one with pictures at each step so I can see exactly what's going on. One thing I need to know from the pictures is how deep and far around to cut
• Most places say to do it while it's still on the tree, but I'd rather do it on a cutting if possible. (I want to do this on a neighbor's lychee tree and it seems to me it's easier to ask for a cutting than it is to ask to leave a blob of tinfoil and shrinkwrap on their tree for a month [and come in an check on it, etc.])
• I know I need "a good branch," but what does that look like? How big can the branch be? If I cut off a huge branch, can I get a huge air-layer?
• Does a place like Lowe's sell plain peat moss? That's really all I need right? Would root growth hormone be helpful? Where would I find that?
• I know spring is the ideal time to do this, but is early summer in Florida fine?

 
Thanks for the help.

I've not heard of air graft. Do you mean rooting a cutting?

Hello,

   I think you mean air layer lychee tree. Here is a link for longan, which is similar to lychee.

Thanks. I'll look at that. Any other advice is always welcome too.

There are numerous you tube videos, check them out then give it a try.
In one they use a sandwich baggie and fill with moist potting mix. They slit
the bag and place this around the branch. This worked the easiest for me.
It was harder for me to take a handful of damp sphagnum moss and wrap
that around the branch. I tried to do four on an Alano sapodilla and four
on a longan. I offered one to the person how owns the longan and he said
sure. I tried to do it a couple different ways to learn and see which way worked
the fastest. The tree will split where you attempt to do this and if you ever notice
the trees that nurseries use the budwood for grafting or airlayers are always bushy
afterwards and eventually will produce more fruit. It doesn't hurt the tree. This is a
great time to do it. The aluminum foil is to keep the sun from drying out the medium
and also to keep excess moisture out. After the airlayer roots and you place in a pot
then keep in indirect light for a couple months for the airlayer to root completely,
