I think your fertilizer routine depends on the fertility of your soil and where you are gardening. When I started my garden, my soil didn't have any organic material in it, so I used fertilizers with higher numbers, but as I've improved the soil, I have gone to lower lower numbers. I also have low levels of magnesium in my soil, so I give the roses a dose of epsom salts in the spring. I am still building my soil, so I cannot rely totally on organics to provide for the needs of the roses.
I also don't treat every rose in the garden equally. Just like people, they have different needs. Anything with large flowers with many petals tend to be "heavy feeders" with higher water needs than your traditional HT or floribunda. It takes resources to generate larger flowers with many more petals on larger, longer canes.
Yes, I do keep garden notes ....
