The best place to put a bonsai tree is in a place where it gets lots of sunlight.
So if you have an indoor bonsai tree it's best to place the indoor bonsai tree near a window that is facing south or near a window that gets the most sun.
The Bonsai Tree should also be kept at a constant temperature for it to grow best.
If you're planting a Bonsai Tree outside plant it in an area where it can get the most sunlight when the sun is shining.
