So below the permafrost, the temperature very slowly increases toward that hot core. The data are courtesy of the West Texas Mesonet. Soil temperatures above 65F are required for significant growth of rhizomes, roots and stolons. Though there have been cases where the frost line extends as far as four feet underground, this is very atypical of Austin winters. In our case, for distance, we are talking about depth in the Earth, and the center of the Earth is very hot about 5000C.
