Hi, I have had my Jade Plant for about 16 years. The actual plant it is about 4 feet high now, stands 6 feet in its pot, and has a trunk 19" in diameter. I was wondering if I should re pot it and when is the best time I last did this about 10 years ago. The plant is covered in pale pink star like flowers twice a year this happens October and June and they last a couple of months at least. Do all Jade Trees bear flowers as often as this? I don't want to stop it flowering by re potting at the wrong time. Also, I have a few yellow leaves at the moment, does anyone have any idea what is causing this?
