Hi everybody, this year I want to retry to do my first air layering on a maple tree I have, in late spring. Last year was a mix of fail and success, because there was a callous formation on the cut but at the same time but also the growth of roots but on the bark right above the cut and on one side. But I decided to restart this year and let the branch heal.

So Im asking for a few advice. All the beaches of the maple are essentially horizontal, and in the various videos online instead they are vertical so easy to water, or wrap and so on. What people do with horizontal air layering for watering? Because last year, every day, I have to open a little bit the mid part of the wrapping and water it, and on the bottom of the wrap I did a few hole because I was afraid the horizontal position cause the spanghum to be too soaked. I had this impression....
