In 1958, Helmut Aurenz, a visionary entrepreneur, founded ASB Aurenz Spezial Blumenerde. Seeing untapped potential in peat moss and gardening substrates, he revolutionized the industry with his commitment to innovation and quality. Today, under ASB Professional, his legacy flourishes. As a global frontrunner, we produce and distribute exceptional peat moss products, potting soils, and specialized gardening substrates. Dedicated to serving the horticultural sector, we design products with professional growers in mind. With our roots in Aurenz's pioneering spirit, we remain a trusted industry partner.
