The theme of the meeting Bay Island Bonsai this month was air layering. It’s a quick way to create new bonsai – much faster than from seed or cutting trees. It is also a great way to correct defective roots as layers typically produces a good base of radial root.

Boon described for us two approaches for all occasions. The first was a technique often used in beechwood. To stop the flow of sap and roots stimulate two aluminum wires are applied adjacent to each other. The wires are properly applied, so that dig in a bit. The area is wrapped in moss to provide moisture for new roots.

The second method is the most familiar of the two – the removal of a section bark below the point where new roots are desired. Stratification is usually performed at two points in the growing season – spring and late spring. Rooting trees easily as glycine or Cryptomeria often can overlap in May and separated in the fall. Maples can be layered in May as well, but it may take two years before they can be separated.

Boon demonstrated this technique to us in a Japanese maple Shishigashira. He started cutting two rings around a branch with a knife graft below the point where the new roots are desired and bark between the rings are removed with cutters knob. Here is the branch after removing the bark.

then, the plastic sheet is filled with wet and wrapped with aluminum wire moss.

Boon then poked holes in the bottom of the plastic with scissors so that leakage of moss.

If this branch cabbage enough roots, which will be removed in the fall or winter, otherwise, will retire next year.
