So I am guessing that it is wise to fertilize plants at all times, provided
that the dosage is slow release and not overdose.

No, it's wise to know your plants and their growth cycles and
nutritional requirements, as well as the fertilizers you use and their
effects.

Gardeners in areas that have severe winters won't encourage growth by
fertilizing just before a season when freezes are expected, for
example.
