I need some advice, as I am new to bonsai, I got this giant sequoia from a nursery online, I live in east coast, I want to create a bonsai out of it. I understand it will be years before it becomes a bonsai. But I want to start the wait in a good direction. Attached are the images. should I chop the trunk from the red mark and use the new growing bud as new leader? Or try to reduce the branches from the top and wait if it create any more new buds near bottom as there are not many branches. This is 36 inches in height and 1-1/4 trunk width, 8 x 8 root ball. Any suggestion are highly appreciated, also is it a right time to just put it in a bigger container without pruning any roots. Thanks in Advance.
