  2. Leon County, FL • Long warm and humid summers; Mild to cool winters; Freezing temperatures occur approximately 52 days per year. • Annual Rainfall averages ~57 inches, with about 50% of the rainfall occurring June-September. • Major Land Uses include urban and built up, residential, cropland and pastureland, pine flatwoods, swamps

  3. Soil 1: From the red hills region of NE Tallahassee Soil 2: From the flatwoods slopes leading to the Ochlockonee River.
