Grapefruit Tree House Plant Leaf Curl And Drop

Question

I have two grapefruit trees that I grew from seed some 60 plus years ago. I live in NJ and the trees live outside during the summer and inside during the winter. One of the trees has leaves that recently start curling and falling off at a rapid rate. I cannot see any signs of infestation. Can you offer some advice? Thank you.

Wow! You've kept those trees a long time. Check out the environmental conditions noted in this article:
