Cassian Schmidt Style Gravel Gardens – A New Effort in Sustainable Gardening with Ed Lyon (Reiman Gardens)
The demand for more sustainable gardening practices has Americans looking beyond this country for viable solutions. A relatively recent trend that is picking up in interest is gravel gardens inspired by German horticulturist Cassian Schmidt and used in municipal plantings that previously utilized heavy water, chemical, fertilizer and labor inputs. The use of gravel and aggregate mulches is an exciting new approach to bring beautiful, biodiverse planting into the city, without the need to hire a staff of highly skilled gardeners. Some of the first were introduced to America by renowned horticulturist Roy Diblik just over 10 years ago with the heaviest concentration in the Madison, WI area. Ed Lyon, director of Reiman Gardens, built one there and brought the idea to the Gardens where the second largest in the country now exists as the Hillside Water-wise Garden. Ed will talk about the attributes of this style of garden and how they are constructed as well as showing established sites.
