My houseplants are withering and dying. Is this bad Feng Shui?

My houseplants are withering and dying. Is this bad Feng Shui?

Yes. If you place indoor plants in a place with fresh air, sunlight, suitable humidity and temperature, where there is no harmful radiation (sha qi), then there is no reason why they do not grow well. What is bad for the plants is also bad for you. Find the cause and do something to heal the house.
