Q.What do I do with a Meyer Lemon tree with curling leaves that are now lighter green than they were?
I have a potted Meyer Lemon tree currently outdoors in Arkansas. I bring it into the garage for winter. I have had it for 1 year. Currently the leaves are curling and a lighter green. I have fertilized and has been watered, as soil dries. It has a lot of blossoms but am concerned about the curling leaves and what to do about it.

This can be due to pests, watering issues and nutrients.
