Regarding variegated pink lemon tree.

Question

Leaves are getting brittle and turning under. Don’t know how old the tree is, acquired it after a couple of days of the weather being pretty chilly. We haven’t had first frost yet, but Claressa to it. It is a potted tree and has about 6 lemons on it. Have never cared for a citrus plant below, so I guess I need beginner’s lessons.

Answer 1

"Leaves getting brittle and turning under" This may indicate water deficit/drought stress from under watering. Or transplant shock from root disturbance if you re-potted it or planted in the ground.
