Orange and mandarin trees

Question

I have a orange and mandarin trees that are not fruiting. The orange tree is more than 14 years old and the mandarin is about 10 yrs, but both of them use to produce abundant fruits. This is the first time they are not fruiting. At the end of last year, I fed them all with citrus feeding granules. I also have lime and lemon trees that are producing lots of fruit. Could you please advise as to how can I resolve this problem? Thank you.

What kind of weather have you had there? A spell of unusual cold might affect orange trees more than lemon or lime. Other than that, you might find some suggestions here: https://www.gardeningknowhow.com/edible/fruits/oranges/no-fruit-on-orange-trees.htm
