What kind of tree is best for feng shui in the backyard?

This cannot be generalized. The so-called Feng Shui is a matter of matching between a person and the environment. For example, if your backyard space is small, you cannot plant a tree with too dense leaves or it is not too shady. In addition, it is also related to the direction, such as Your house is upside down from the north to the south, and the backyard is to the south. A tree with red leaves in the middle is likely to cause trouble.
