Why do we grow trees that are not hearty in our biome? beats me, but we do. I know this is going to seem like not an answer
to your question, but let me digress.
Littered on every bonsai forum I have read over the past 15+ years is filled with the failures of new growers who don't know what the horticultural needs of their trees are.
The mummified corpses of ficus and juniper I have taken out of pots, in order to recycle the pots exceed a hundred.
Trees don't live in the absence of temperature, seasonal, and precipitation cycles.
The shortest and most direct line to your success isn't going to be in two hundred word replies on the internet; but to visit your closest arboratum or bonsai nursery, and do nothing but ask questions or wash pots for them for a year or two.
Every thing you think you know about gardening does not supply a trees needs indoors.
Bonsai growers who persist kill a lot (often hundreds) of trees learning how. And that is with growers who keep their trees out of doors. The toll in dead trees isn't less indoors.
Bring your eyes the first time you go to an arboratum, it should suggest whether beer or coffee will be your best bribe on second and subsequent visits.
Every municipal, state, or federal, garden that houses a bonsai collection is under funded and is very suseptible to the offer of volunteer labor.
You both got what the other needs, make it work.
