I purchased a Dwarf Jade Tree in the first week of April of 2014. For about the first two months it seemed everything was going fairly well, the plant was healthy and showed no signs of anything being wrong with it. The last week in June things started to change with my tree though. Almost all the leaves have fallen off except for maybe Id guess twenty toward the top region of the tree. I have checked the tree for bugs and there seems to be none that I can see. I think the problem is that I may have over watered and it may not be getting as much sunlight as it should. I don't know if these two things would cause almost all the leaves to fall of the tree, so if anyone has any knowledge to inform me of or suggestions on what I should do I'd very much appreciate it. I would be so sad if my Jade would happen to die, I'm just out of ideas on what to do to help it get back to a healthy state.
