(B) Reason for dying polka dot plant
1. Extra water
Polka dot plants need moist soil to grow happily. But if you give more water to keep the soil moist. This will make the soil waterlogged and this waterlogged soil is the main cause of the dying polka dot.
The soil must have water-absorbing material like perlite. Also, have some well-draining material that allows the extra water to drain out.
Remember that plant roots need fresh air to work properly. When roots do not get fresh oxygen, they get infected by fungus.
Once the roots get infected by the fungus the plant starts dying.
