I have a small pink lemon tree in my yard, more of a small shrubbery at this point actually, and it made it through the winter I think, well better than my Mango and starfruit anyway. It has three leaves on it but is putting out lots of flowers. At this point in the season all of my other citrus trees have lots of new leaves barring an older Shiranu and/or small fruit. My non citrus are a mixed bag but for the most part seem good with no problems. So whats going wrong with the pink lemon? The three leaves have some kind of milky film covering part of the green under the surface. I have added fertilzer and coffee grounds and water isnt an issue.
