As an older rookie to bonsai I see a big advantage to air layering as opposed to growing from seed. I have watched several videos about air layering and have the basics pretty well down. The problem is most of these videos don’t cover the details I need. I want to know if it is too late in the year to start on Elm, Hornbeam or Crab apple trees? Is there any branch diameter that is considered maximum. Why do some people fasten a wire around the top of the layer? Any help will be appreciated.
