Edm. Romberg & Sohn (GmbH & Co.) KG is a specialist for plant cultivation and horticulture. The company, established in 1865, is headquartered in the town of Ellerau, not far from Hamburg. The wholesaler sells products intended both for hobby gardeners and for the commercial horticulture industry. As early as the 1950s, the company developed novel growing systems for professional horticulture and was thus able to quickly secure a leading market position. The product portfolio includes Bollerbloom products for plant growth, such as soil and growing pots, as well as foils and plant protection materials by Covergaard. Customers looking for a greenhouse or a heater can purchase products made by Powerplaant. The company regards the careful use of natural resources as an important part of its corporate philosophy. Starting from 2010, Romberg has been converting all of its peat products to coconut fibers. The reason for this is that coconut use is carbon neutral because coconuts are a renewable resource - in contrast to peat, which causes high levels of carbon dioxide.
