    It is a great idea. But how do you build a root cellar in the san antonio austin area? Ground can become rick hard with heat or nothing but very wet slushy mud when we get lot bouts of rain or the effect of hurricanes striking the coast

      That’s a tough combination that you are contending with, heat and humidity. The soil conditions would be a problem, I think in your case while it would be a hassle to deal with you would probably need to build one above ground with powered ventilation.

      It’s possible underground but your just contending with so many elements. You’d have to dig pretty deep 12-13 feet to bypass the heat, but the temperature is always fluctuating. I believe you encounter more difficulties with underground storage than an above-ground one.
