Dwarf shrubs will not have any impact on Feng Shui. There is a saying in Feng Shui: I would rather treat a thousand bamboos (dwarf) than a tree (big tree), which means that short shrubs have no impact on Feng Shui. If you are not at ease, you can use the white tiger mirror to crack it. Method: hang a mirror at a suitable position at the door, adjust the angle so that the shadow of the shrubs is reflected in the mirror.
