|the leaves are dropping off rapidly what can i do to save this plant?|
|Jades will drop leaves for many different reasons, not all of them bad. Unless they are pruned regularly, they will periodically "self-prune" by dropping off older leaves so that new ones can grow in. If your plant is otherwise healthy and nothing has changed in its environment recently, then that may what is happening with your Jade.
Improper watering is also a common cause of leaf drop, particularly overwatering. Large, mature Jades rarely need repotting. If they are unnecessarily repotted, the excess soil that is added can retain moisture for too long and gradually rot the roots. Often the first symptom is leaf drop. I hope this is not the case with your Jade.
Good light for a Jade means right in a sunny window that gets direct sun for at least several hours per day. Inadequate light will cause some leaf drop, but will not kill the plant. I hope this information helps you determine just what might be happening with your plant.
