layering was dane in the previous year。
Good equal root is made of beech when layering is done in the way of joining wire. Copper wire is wound around the position where it wants root shown as much as to cut into the trunk. It is point that is strongly tightened. Sphagnum moss is put on that, and covered with plastic bag.

It waits until the next year if root doesn't come out in September.
Thinking that it takes one year, let's do it.
