Placement in the pot is very important.
There are a number of “rules of thumb” to go by:
Round (or square, or hexagonal), the tree should be planted in the middle of the pot.
Ovals or rectangles, the tree should be planted slightly off center when viewed from the front. When viewed from the side, the trunk should be planted on the centerline. Not towards the rear.
At one time, the “rule of thumb” was to plant the tree towards the back of the pot, not on the centerline. And, the rule was to pot farther off to one side or the other, not “just off center”. The “rule” has been changed in recent years. Why? For the health of the tree.
A centered tree is more likely to have an even distribution of roots all around, and not have a one sided root system. Potting close to an edge of a pot can (will) suppress the root system, and can adversely affect the health of the tree.
On a tree like Bonsai Nut’s tall conifer, it’s ok to plant it very off center for a show, but it shouldn’t be kept like that permanently.
