Is there a way to tell when fruit/trees are in season?

I've gotten myself an orchard going of all different sorts of fruits and nuts growing, but I'm having trouble remembering what grows when. Is there a way to tell when the tree is in or out of season so I don't waste fertilizer on trees that aren't producing?
Other than obviously "this tree is growing fruit, it's in season". I'm looking for more along the lines of how to tell what season the fruit is by the look of it's tree or something.

Outside of growth stages and simply knowing what trees are in season, you can't really tell whether a tree is in season. However, even if a tree isn't in season, fertilizer still increases the quality of the fruit produced, so it never really goes to waste.
