Now I want bonsai. So my lowest branch (to leave on as a stimulator for new growth), and your lowest branch, might not be the same.
More than root stimulator you need very fast draining soil for your pot.
An example: one part crushed bark mulch, one part crushed *granite grit (grani-grit is one brand name). AND 1/2 part peat. Osmocoat pellets in spring after growth starts again.
*Grani Grit is a a poultry scratch. get yours at the feed store...
I have bought in bulk (by the ton) at the gravel mill.
