A friend of mine gave me well-established lime and lemon trees. They're about four years old, two or three feet tall. She's moving and can't take them with her. The lemon tree is doing relatively well: it's lost two leaves in the last ten days.
But the lime tree isn't doing well at all. It's dropped more than half its leaves. They seem fine, nicely green and healthy, but then just drop off. It has the same light conditions (we both have windows facing the same direction), and I'm watering it on the same schedule as she was.
Could the stress from the move (about ten blocks, walking) be causing this? How can I help it recover? I'd really like to see it healthy again.
