Grapefruit Tree shedding Leaves
My potted 6 ft. tall, 10 year old Grapefruit tree began dropping a lot of healthy-looking leaves lately. It thrived in a hot summer outdoors, until the temperatures started to drop in October, and I brought it inside. After 5 or 6 weeks indoors, the leaves started dropping. I watered the plant once a week since I brought it in. Any suggestions?
