My Ficus keeps losing leaves due to an unknown reason. The leaves turn yellow, and then brown, and then to the slightest touch, just fall off. I’ve looked everywhere and can not figure out what is happening! I’ll change the soil tomorrow, and I hope that will help! I’ve also tried more water, less water, pulling off old leaves, and nothing seems to work. It keeps spreading up the plant, and so far I’ve lost almost half of it, and I don’t know why. Any other ideas? I’m really needing some help! I just took a closer look, and it seems as if my plant has a disease!!?
