Will putting some fake flowers and grass at home affect Feng Shui?

Flowers are mainly used to promote peach blossoms in geomantic omen. If the position is not properly placed, it will lead to rotten peach blossoms for the corresponding people. Artificial flowers are used for decoration, and their function is to enhance aesthetic feeling, so they will not affect Feng Shui. If fake flowers affect Feng Shui, is the painting of rich flowers fake? Why is this happening? Isn't it just slapping your mouth?
