If you wanted the apple *and* the ground in focus, you would want to stop down your aperture (make your f/# bigger). The bigger the f/#, the greater your depth of field (DOF). Depth of field is how much of the photo is in focus. Small f/# = shallow depth of field = little of the picture in focus. Big f/# = wide depth of field = more of the picture in focus.
If you just want the apple in focus, Tyler is right, you just missed the focus and need to make sure that your auto focus lights up on the apple, not the ground. Or manually focus.
I agree that a fresh apple with lots of color would be better, but I applaud the idea. To be honest, I was almost expecting a photo of a macbook or something, lol.
