I have a kaffir lime plant in a pot which I have had for about 3 years. Every summer it lives outside on my deck (central NJ) and I bring it inside in the winter. It has always been very healthy, producing lots of shiny new leaves and shoots. When I first brought it inside this fall, it dropped a lot of leaves, but has been stable until the last week or so. It is now dropping dozens of leaves each day, and if I gently touch it, lots more fall off. What can I do? Some of the branches are now completely bare. Should I trim them back? I can post a picture if it would be of use.
