If you've dug in San Antonio soil, you know about caliche: that hard, crusty layer that's tough to break through. It's limestone-based and common in our area, and it can really affect how trees grow. Trees that hit caliche struggle to develop deep root systems, making them more susceptible to drought stress, wind damage, and shallow rooting issues.
The good news: knowing about caliche helps us make smarter tree choices and care decisions. Some trees adapt well to caliche-heavy soil, while others will never thrive in those conditions. If you're planting new trees or concerned about existing ones, understanding your soil profile makes all the difference.
Our ISA-certified crew can assess your soil and recommend trees that'll succeed in San Antonio's specific conditions. Call Texas Tree Authority at 210-251-4232 for expert guidance. Have you had soil testing done on your property, or do you know what's under your trees? #TreeCare
