Hello, I have a Star Jasmine plant that is seven years old. I bring it indoors during the winter and bring it out in spring. It blooms every year in July and has been very robust. Last fall, I re-potted it as it had grown substantially. I brought it outside in May, and it again bloomed in July. However, some leaves began turning reddish yellow and falling off. I did a bit of research which suggested the soil was too wet. Indeed there was standing water on the soil and I realized that the pot had no drainage. I drilled holes in the bottom of the pot to drain the soil and the condition persisted. More research suggesting removing a large quantity of the dirt and exposing the root ball to help dry it out. The soil is now dry but leaves continue to change color and fall off. I fear that I allowed the wet soil condition to persist too long and have done irreparable damage. Or, is it possible that a fungus or other anomaly may be effecting the plant. Please let me know your thoughts, and thanks.
