Healthy growth of trees

If it is too small, don't trim it yet. Just put it in weak light and scatter light at the contact point. It's wet and dry when watering. When it is too big, it will be trimmed. First pick the core to make the branches and leaves below get enough nutrients, and then slowly cut off the excess branches. It's too small now. I suggest not pruning the branches yet. I hope I can help you.
