Friday, April 14 & Saturday, April 22 | Soil is a living matrix of chemical and biological interactions, and a fundamental understanding of soil science is critical when selecting well-adapted native plants or choosing amendments needed by native plant communities. This two-day, hybrid class for the ecologically-minded grower, will discuss soil texture, chemistry, water-holding capacity, the biologically diverse life in the soil, and how these dynamic relationships can affect a plant’s health.

Wednesday, May 17, Saturday, July 8, & Wednesday, September 13 | Presented in three parts, native plant expert Dan Jaffe-Wilder will introduce students to a wide variety of native perennials to use in a number of garden settings. Class sessions during May, July, and September will feature native plants and an overview of an extensive range of seasonally-relevant perennials. Discussion during online lecture and in-person field-study will include how to select the right plant for the right place in the right combination, cultivation variables, choosing plants for their ecological role, specialized garden communities, aesthetics, propagation, and proper plant procurement.

Friday, June 16 & Saturday, June 24 | Ecosystem balance, soil, and water quality are all influenced by our landscape practices. This extensive, two-day sustainable horticulture class will help students apply the principles of ecologically safe gardening practices to their garden or landscape. Through online and in-person sessions, we’ll examine composting, techniques for eco-friendly soil amendments, alternatives to pesticide and herbicides, responsible native plant acquisition, erosion control methods, plant forms for function, and so much more.

Friday, September 1 & Saturday, September 9 | Over two days, online and in-person, learn about native woody plants that contribute so much to our landscapes and local biodiversity. Andy Brand, Director of Horticulture at the Gardens, will discuss identification, habitat, and the role woody plants play in plant reproduction and management as hosts for insects, birds, and other wildlife. Online and in the field, Andy will recommend native species and cultivars, and explain cultivation, landscape uses, and soil and light considerations.

Friday, October 20, Friday-Saturday, October 27 & 28 | To design landscapes inspired by—and inclusive of—nature, study essential design principles through the lens of natural systems. In this three-day course led by landscape architect Lisa Cowan and landscape designer and horticulturist Irene Barber, students will learn to identify and incorporate the components of ecological landscape design. Online and onsite, examine the systems influencing design decisions, practice environmental site analysis, and design conceptual plot plans for a selected site.
