My tree was healthy last year, got great fruit, it is about 10 years old. I fertlized 3x this year. However right now the fruit is tiny, the leaves are yellowing and falling off. It looks sick...right next to it is a healthy dark green leafed grapefruit. I don't know if I should fertlize now with our winter upon us, but I know it needs something..I just don't know what. I have not seen any sign of pests or fungus. Suggestions please
Thanks..that is exactly what it looks like. I sure hope thats NOT it. Going to call extension service today.
