San Antonio's summer heat is testing even the toughest live oaks this year.
Thin caliche soil holds onto very little moisture, so triple-digit stretches show up fast as leaf scorch, early leaf drop, and thinning canopies across the city.
A stressed tree does not always look obviously sick. A slightly duller canopy or a branch going bare earlier than the rest of the tree can be the first sign worth a closer look.
Heat-stressed trees are also more vulnerable to pests and disease they would otherwise fend off on their own, which is why early attention matters most right now.
