Having a problem with Serissa dropping leaves after moving indoor and re-potting. I,m in NY-Long Island area and had this tree outdoors all summer where it was in good light with watering from sprinklers system almost daily. Had good new growth and appeared very healthy. I moved it indoors to a southern exposure window and it began to drop leaves. Took it to my local Bonsai dealer and he recommended re-potting, which I did with his soil mix which is good draining, and roots looked good. Afterwards it continued to drop leaves. I water about every 2-3 days when the water meter drops to just above the red zone. I have been feeding it with Bonsai fertilizer and used Super thrive vitamin after re potting. I had the same problem with this tree last winter while indoors. Any suggestions? Hate to lose this tree.
