The first mistake is heaping fertiliser at the trunk. Absorbing roots sit under the drip line, not at the collar; material dumped at the base is never taken up, and it traps moisture and heat exactly where fungal infection starts. The right placement is a wide band out at the canopy radius.
The second is feeding into dry soil. Organics need water for microbes to work; on dry ground the material simply sits until the first rain, and the nitrogen lost to the air in between is gone. Feed ahead of rain, or irrigate straight after.
The third is leaving it uncovered. On an open surface pellets lose nitrogen to volatilisation and wash away in heavy rain. A thin layer of soil, or a mulch of plant residue, is enough.
The fourth is putting the whole year into one application. Organics release gradually, so splitting into two or three rounds by growth stage does more with the same total. The fifth is switching product mid-season because results feel slow — an organic base needs at least a full season before it can be read.
