Q.Lemon Tree Root Rot
I transplanted a 3yo lemon tree in our yard two months ago. It’s a Meyer hybrid. After transplanting we experienced some cold weather (5 degrees Celsius) and a lot of wind. Many leaves have since curled and fallen off. Currently just one healthy leaf remains. I posted pictures of the healthy leaf, a curling leaf, and a brown leaf, as well as the stems. I’m concerned about potential Root rot. Can this tree be saved?
