apricot growing problems

(L.A.)

I have and apricot growing proble. I have an apricot tree, which blossomes at summer time(not spring) , then i see a few apricots. It is about min. 5 ys. old. Close to that one there is another one, which blossomes at spring and has enough apricots. Both of them at least have 3 times fertilizer and te same weather. They are located at L.A.

Please tell me why it blossoms i the summer time and has only a few aprictos and does not keep the blossoms.

Thank you. Peter
