The potted plants in the house are dying one after another. Is it because of bad feng shui, bad house layout, or other reasons?

I don't believe in Feng Shui, but I believe in planting techniques. A plate of plants in the room needs manual management. If you don't take care of them, you will die. People who love to grow flowers often love them very much, take care of them too carefully, water them often for fear that they will die, and close the windows in their rooms for fear that they will freeze to death. These are all bad phenomena and precursors that often lead to plant death. Too much watering leads to the death of rotten roots, and closing the window leads to the failure of plants to grow.
