[IBC] Fertilizer
I am wondering if some of you discuss some of your fertilizing
techniques and the brands you use. ============ Brands don't matter. One commercial fertilizer is as good as any other, despite their advertising claims. A few, like Osmocoat, can be a bit dangerous to use in bonsai and should be used very sparingly, if at all, but of the non-time-release fertilizers, get whatever you find on sale. What is important is the NPK content. Generally a balanced fertilizer (where the NPK is in an approximately 1-1-1 ratio -- the most commonly found is 20-20-20, but others that approximately balance, even a 1-2-1 ratio, will be just as good, though the P can build up in soil. Many claim that a high P and K and low N fertilizer should be used in the fall, but I have never seen anything that makes scientific sense to justify that for me. Fertilizers used for Azalea (and other ericacious plants) should have NO nitrate nitrogen, but beyond that it doesn't matter much what form it (N) comes in. I like to use organic fertilizers with highly INorganic bonsai soils, on the theory that the organics tend to adsorb to the surface of the inorganic materials and hang around a bit longer than if you use inorganic fertilizer with inorganic soils. Most organic fertilizers are low (or lacking) micronutrients, though, so you will have to add iron, manganese, magnesium, etc. or (best) occasionally use a fertilizer that contains the necessary elements.
