Please help! I am looking for a children book

Okay I have question friends, there's a book I have been trying to track down for months-the problem is I dont know the name. Its a children book it was my favorite when i was at jackie robison acadamy in mrs,mraghetti class*i think it was 3rd grade* anyways its about a talking apple tree, a worm that live in the apple and the how the season change and affected the apple and the worm. Anyone have clue because thats all I got, I google it and no luck since I dont know the name, so frustrating.*its not The Giving Tree nor The Seasons of Arnolds Apple Tree) thank you
