I have a potted Arabian jasmine that I winter over indoors. This year, after about 4 winters, I nearly lost it. The leaves yellowed and gradually dropped off. The yellowing leaves were still green at their veins. After repotting in fresh mix and a bigger pot it's recovering and blooming better than before. I suspect hard water was the culprit, and I'm now watering it with condensed water from the dehumidifier. Does this ring any bells with any of the more experienced jasmine lovers out there?
