2. Solutions
If it is caused by too much watering, it is necessary to control watering, but if the curling is too serious, it is necessary to take it out of the basin, and then put it in a cool place to dry before serving the basin; if it is caused by too little watering, it is necessary to appropriately increase the amount and times of watering.
