Seeds germinated and were repotted this spring. Some have come out nice and straight with a low branch split, some have curvy trunks that will not work for a formal broom.
I have tried this before a few years ago but the growth was poorly managed and ramification was too coarse. Maybe restricting growth initially is the trick?

Does anyone have experience growing shohin Zelkova bonsai? I am keen to see if there a is a good model to follow. If I could have this in 10 years I'd be stoked
