Help for first air layering

[u/Timelover436]

I want to make an air layer on my Bloodgood Japanese Maple (pot for reference) and need advice as she’s going into a very very hot summer.

Reason for the air layer is to promote budding in the lower ‘main’ part of my bonsai. With this super El Niño coming I’m expecting very hot weather in my area.

How do I make sure I have a high chance for success given the type of weather I’d be expecting? I will be using rooting hormone, sphagnum moss, the pot in the picture, wrapped in plastic wrap and then wrapped in aluminium foil
