Why Would the Leaves of a Recently Planted Lemon Tree Be Curling?
Transplant shock is a likely cause. Make sure that it gets enough water. Be sure that you are not planting it too deep, you want the ground around the tree to be about the same level as the ground and not in a hole or piled up around the trunk of the tree. If you didn't get enough root, that really hurts, but can be survivable. Having said that, do not over water it either. Make sure the ground isn't muddy around it (except for immediately after watering).
