I think most people tend to over fertilize, and I know I did until I took
the Master Gardener classes from our county extension service.

Perennials need 1-2 pounds of nitrogen per year, in a slow release form.
All of the organics are automatically slow release because they depend on
microbes to break down the organic material.  As to the rest of the
nutrients needed, the very best bet is to send a soil sample to your
land-grant college to be tested.  Call your county extension service for
more information.

The rule we were given is "Test, don't guess."

Annuals need more fertilizer, but I am not sure how much.  Trees and shrubs
need very little in most soils.
