Hello everybody! I've bought recently a pre-bonsai but I really don't know how to proceed for the setting pruning...
Do I have to cut two of the three branches? Or I've to leave everything as it is for another year (to let the trunk grow)?

Thank you very much for your help!

The main problem with this plant will be the graft. It is very high up the trunk and it looks bad. I hope that you only took this inside to take pictures and are not going to try to keep it alive in a house. I would plant it in the ground for at least two or three years to get some girth into the trunk, and just allow it to grow unchecked. I might make a reasonable garden tree but not bonsai.

One of the main things to do in any case is to reduce all the intersections to max 2 branches. MOre and you are setting yourself up for bulges and inverse taper.

Ugly grafts can often be overcome by layering the plant off. But for now, reduce the branchintersections. Consider initial wiring. Then let it grow.
