If you've ever tried to dig a planting hole in San Antonio and hit a layer of chalky white rock a foot or two down, you've met caliche. It's common across the area, and it makes life harder for young trees trying to establish a root system.
Caliche is dense and poorly drained, so roots can struggle to push through it and water can pool right where a young tree needs it to soak in. A tree that looks fine at planting can end up stunted or stressed a year or two later if the hole wasn't prepared for what's underneath.
Breaking up the caliche layer, amending the soil properly, and choosing species that tolerate it well all make a real difference. It's one of the reasons a planting job in San Antonio isn't the same as a planting job somewhere with normal topsoil all the way down.
Have you had trouble getting a new tree established on your property, even after watering it regularly?
