How can I tell if my kalanchoe plant has been overwatered and what steps should I take to remedy the situation?

You can tell if your kalanchoe plant has been overwatered if its leaves are turning yellow or becoming mushy. To remedy the situation, you should stop watering the plant and allow the soil to dry out completely before watering again. Ensure that the plant is in a well-draining pot and adjust your watering schedule to prevent overwatering in the future.
