In 1925, Strachwitz and his family moved from their palace in Groß Stein to their manor in Alt Siedel, because of personal differences with his father, who remained in Groß Stein. Between 1924 and 1933 Strachwitz founded two dairy cooperatives which many local farmers joined. In parallel he studied a few semesters of forestry. He used his knowledge to influence the Silesian forest owners to sell their wood to the paper mills. He continued to use his influence in Upper Silesia to modernize forestry and farming. His ambitions were aided by his presidency of the "Forstausschuss" (Forestry Committee) of Upper Silesia and his membership in the "Landwirtschaftskammer" (Chamber of Agriculture). Strachwitz completely took over his father's estate in 1929, first as the General Manager and then as owner, with full responsibility. This made Strachwitz one of the most wealthy land and forest owners in Silesia. Along with the palace in Groß Stein he owned a lime kiln and quarry in Klein Stein—present-day Kamionek—and Groß Stein, a distillery in Groß Stein and Alt Siedel.
