General purpose fertilizer is a myth, much like one-size-fits-all.

Without knowing what your soil is lacking, 13 is just a random number, and
it doesn't make it any less random just because they picked it for all
three components. Also, those three components are only a slice of the
many things soil needs to be a healthy growing medium.

If you're going to just use one "general purpose" thing without having any
knowledge of what the soil already has, and what it's lacking, use compost
instead of a random synthetic fertilizer blend. Otherwise get your soil
tested so you can tell us what it needs.
