Acer P, Propagation from Cuttings
“The Beauty of Acer Palmatum”, Harumi Miyou, Bonsai Today 64, 1996
Propagation from cuttings:
Best time of year: before spring budding, or summer after shoots are matured.
Use branches that split in two; choose central parts with the shortest internodes—let one grow as a future sacrifice branch, so the base will thicken quickly.
Straight cut or slight angle
Clay pot or wood box.
Drainage layer on the bottom. Recommends sifted fine akadama, but place the sifted dust back on top.
Spring cuttings that root may transplant the same fall—plant in individual pots.
Balance roots so that one or a few are not longer or stronger than others.
