Lemon tree leaves curling

Asked September 9, 2017, 11:11 AM EDT

We have had two varieties of lemon trees in pots -- Lisbon and Meyer -- for several years. Outside in spring/summer/fall inside in winter. This year both produced good new leaves while outside, but these then curled inward from the lateral sides toward the midvein. Have stayed that way for some time. Do you know what causes this condition and do you think they will eventually open up?

Thank you for including an image of your lemon tree with your question.

Lemon tree leaves are known to curl upward when the tree runs short of water.

Lacking a time line of events, my best guess is that the tree ran short of water when the leaves were very new but not yet fully developed and turgid. Thus, the upward curl became permanent. Those leaves won’t unfurl. Even so, it’s important to retain them because they are green and are photosynthesizing on behalf of the tree.
