In my eyes this fertiliser thing is really quite simple. once you have figured out what the main constituent elements of most fertilisers do, it is easy to apply this to the purpose of what you want to achieve.

Nitrogen is used by plants for leaf growth, Phosphorous primarily for root-growth and Potassium mainly for flower and fruit production.

For example, to bulk up young plants give plenty of balanced fertiliser during the growing season and increase phosphorous in autumn to build up root strenght for dormancy and the spring push.

There is planty to read up on this subject but it all boils down to the simple statement above. I do not believe it really matters what brand the fertiliser is, as it's the balance of NPK that does the work.

Good point by Bart about the trace elements though- I think some more reading is required for me to cover that.
