Answer 1

There is something in its care that is lacking. Read the cultural needs below and see where there is a discrepancy. It may be overwatering or overfertilizing. Let the planting medium dry somewhat before watering again. Many plants suffer from a change in environment, from the nursery to your home or outside.
