Hi people, can you throw some more specific brand names-products out for the inexperienced like myself. Also a few plant species next to what you would use the fertilizer with. Pines, Ficus, maples, pomegranate..

you are trying to make something that is simple into something that is far too complex. All my trees get the same fertiliser. Far too complicated to have a different sort for each different tree and when you get down to it they are all trees so all they really need is nutrients. On the question of what fertiliser - It does not matter

None of my plants can read so they cannot tell what fert I am applying. All they are interested in is the nutrients and all the different brands have nutrients in them. I use whatever I have on hand at the time but try to use a range of different ones like powerfeed one time then soluble fertiliser the next time rather than using the same one every time. This is just in case a particular fert is a bit short in any particular nutrient or trace element (eg blood and bone has good N and P but little K) You will note that in this post Treeman has said that he is also using several different types, presumably to give a wider range of nutrients and trace elements for his plants.
