One of the most beautiful and famous gardens in Germany uses steam as a comprehensive means to control weeds. The so-called dahlia hill was treated sucessfully with steam after other means of weed control had become ineffective and too costly.
In June 2010 Isle Mainau asked the company mobildampf.de to gradually steam flowerbeds of altogether 2000 m² via sheet steaming.
Within just 3 days and after about 50 operating hours the area was sterilized using 2 steam boilers. Among was one steam boiler type S2000 produced by MSD / Durbach with an output of 2000kg steam/h. The beds were steamed down to 30 cm depth reaching a temperature of 85°C.
Within the upcoming years weed pressure on the dahlia hill has been effectively resolved.
