How about planting trees in the wall of the shop with geomantic omen?

Planting a tree in the wall of the shop is good for geomantic omen. Because trees are considered as a symbol of wealth, and small green trees are even more a symbol of good luck.

However, if trees grow on the wall and cause cracks or instability, it may be necessary to consider removing or repairing the trees. In short, when judging Feng Shui, we need to consider the position, size and shape of trees and their relationship with the surrounding environment. It is best to ask a professional Feng Shui master to evaluate them.
