I have a lemon and lime tree that I had brought in for the winter a while ago. They seemed to be doing well, but lately the lemon tree has been dropping leaves, and when I came home from being gone a couple days the lemon had dropped a lot of leaves and looks really droopy. Is it not enough water? I cut down on watering because they’re supposed to be dormant for winter and Planta is suggesting water pretty infrequently. I’ve been doing about a cup or 2 of water each watering (Planta tells me to water a couple of weeks apart). Is this able to save?? What can I do? 😢
