The most common cause in San Diego is water, either too much from a leaking or overzealous irrigation line, or too little during a hot dry stretch. Beyond water, fungal disease, boring insects, soil compaction, and grade changes over the roots all show up as yellowing and dieback. Because the symptoms overlap, guessing wastes money on the wrong fix. A proper diagnosis checks each cause in order before recommending treatment.

A certified arborist inspects the whole tree, the canopy for dieback patterns, the trunk for wounds and decay, and the root flare and soil for water and grade problems. We look for the specific signs of the local pests and diseases, from the oak borer to shot hole borer to palm weevil. You get a written diagnosis with a clear plan of what to do, whether that is a watering change, pruning, soil work, or removal.

Many can, when the cause is caught early and corrected. Water and soil problems are often reversible once you fix the irrigation or relieve compaction. Some fungal and insect problems can be managed, while others, like an advanced borer infestation, are not curable. The value of a real diagnosis is knowing which case you have, so you spend on trees that will recover and plan removal for the ones that will not.
