Not every tree needs fertilization, but many in San Antonio's compacted, alkaline urban soils are working with far less than what they would have access to naturally.
Cedar elms and live oaks in particular often show slower growth, thinner canopies, or pale leaf color when soil nutrients run short. A proper fertilization program targets the root zone directly, rather than just feeding the surrounding lawn, and is timed around the tree's growth cycle rather than applied on a generic schedule.
Fertilization is not a fix for a tree already in serious decline from disease or root damage; it works best as ongoing support for a tree that is otherwise healthy but stressed by its growing conditions.
If a tree's growth has slowed or its canopy looks thinner than it used to, soil and root health are worth checking before assuming the worst.

Authentic photo preferred: root zone fertilization equipment in use, or a healthy, full canopy tree that shows the result of ongoing care. Before/after canopy density comparisons work well if available.
