Hello, I've had this jade for about 6 months, I got it from a friend who was moving away and could not take it with her. Recently it has been losing more than a few leaves a week. They are wrinkling and then drying up before dropping. From research on how to take care of it I give it water every 1-2 weeks allowing it too dry out in between. Its at a northern window so it gets decent sun. I used home remedies to get ride of a small mealybug problem and im hoping this isnt the cause of my concerns. Any advice helps, thanks!
