I bought a five-year-old Japanese white pine (five needle) tree that came with a pot that I don't quite like so I would like to change the pot to a similar sized one, but I've heard you're only supposed to "repot" in late Feb/March. Is it okay to just change pots without removing any roots into the different pot or should I wait? I live in Tokyo so the weather isn't THAT cold...I think.
Because it's 5 years old or because it's still winter?
So JUST changing pots without trimming the roots is still dangerous?? I thought the reason it was dangerous was because you also trimmed the roots as well.
