bonsai barry

I tried air-layering several trees. In three cases, all the growth above the cut died. Does this mean that when I cut my ring around the tree it was too deep?
Sounds like it.
What kind of trees were they, and what hormone did you use?

What were you using as a substrate and did you allow it to dry out at any time. Is there callous formed at the cut or any signs of roots that started?
