Q&A from Rakuyo:
Weak Trees
Move to shade
Do not over water, extend the drying period (tip the pot on one end)
Recommends fertilizing well, liquid
Fertilizing
Generally micro doses MiracleGrow (blue crystals) during watering.
Liquor Fertilizer (fish emulsion) weekly full fertilizer during growing season.
Finds organic, tea bags or Osmocoat may not be enough—unless a lot of slow release fertilizer and well distributed.
Taper
Chop after the trunk is at least 50% of the final desired diameter.
