Siemens first learned agriculture and managed goods in Hanover between 1828 and 1832. After long trips through Bohemia, Moravia, Hungary and southern Germany, he worked as a distillery administrator and in 1837 built the first larger sugar factory with a steam facility in Braunschweig. In 1838 he became a teacher for agricultural-technical trade and head of the chemical-technical workshop at the Royal Württemberg Agricultural and Forestry Academy in Hohenheim . There he became a professor of technology in 1839 . In 1868 he charred and revived bone charcoal in ovens with standing retorts (so-called Hohenheim ovens), which the ovens from Schatten, Gits & DuRieux and Brison were modeled on. In 1882 he retired and from then on lived in Bad Harzburg. For his scientific merits he was raised to the Württemberg personal nobility.

He was married to Ottilie Denzel (born March 8, 1812 in Heilbronn, † October 18, 1882 in Charlottenburg). Her daughter Antonie Siemens (born September 16, 1840 in Hohenheim; † December 22, 1900 in Charlottenburg) was married to the inventor and company founder Werner Siemens , a third cousin of Carl Georg, from 1869 and received the Prussian nobility through him in 1888.
