Hello! I plan to grow a Tangerine bonsai tree but I'm unsure as to what soil I should use once I transfer it to a training pot. Should I use a purely inorganic mixture, purely organic mixture, 50/50 or some sort of percentage mixture, or All-Purpose blend? If anyone has any specific product recommendations feel free to name them or post a link.

Thanks in advance!

The best soil is not only dependent on species but very much on care and environment. I keep my citruses in 80% organics with bland in pumice. The trees is kept in 5c all winter with absolutelly no watering. Winter is 5-6 months here.
