Just bought a Japanese Maple (see first link) and want to eventually turn it into something that looks kind of like the ones shown in the second link. I know it’s going to take years, and its not ideal growing Japanese Maples in LA (not enough dormancy, temp change etc.), but that’s my goal. Don’t currently have room to plant it in the ground, but might be able to within a year or so.
From what I understand, I have to let it grow for years, until it reaches the desired trunk size after which time I should do a trunk chop? The trunk has some decent movement, but not sure if it’s enough and if it will translate well when the trunk thickens. Any advice on that?
Should I repot next year?
As I’m letting it grow, do I trim any of the side branches? Do I worry about the roots at all at this time? Do i try to shape/wire the branches?
Also, I know it needs shade, but do I give it any partial sun or do I keep it in the shade at all times?
