Hi I have a lemon tree it has no leaves will the leaves grow back its been outside since October in a zipper bag. Its in the bathroom on the window sill
Scratch the bark lightly. There's still life in it and may be able to make a comeback if there is green underneath. Give it as much light as possible. Reduce watering to a minimum due to lesser demand for moisture from loss of leaves. Do not fertilize until it shows signs of recovery.
