First sign of over-watering is yellow or brown leaves that fall off before drying. Since different types of palms have different water requirements, it’s important to know what kind of palm do you have.
As a rule of thumb, palms need to be watered more in the summer, during their growth season, and less in the winter. They like moist but well drained soil. To solve this problem, you can add 30% sand & 30% grit to the soil to provide a good drainage.
