Soil Science for Gardeners

This in-depth class for the ecologically minded land steward and gardener will delve into the properties and functions of the living system of soil. A fundamental understanding of soil science is critical in selecting well-adapted native plants or choosing amendments to mimic the natural conditions needed by various native plant communities. Students will gain an understanding of soil texture, chemistry, water-holding capacity, and how these factors influence a plant’s health.

Horticultural Ecology

Wednesdays, September 1 and 8

Explore the ways in which plants interact with their garden environments. Join instructor Dan Robarts as he discusses specific adaptations to environmental conditions; interrelationships between garden plants and their surrounding biotic and abiotic influences; and concepts such as competition, symbiosis, parasitism, pollination, and dispersal. The first session consists of an online slideshow and introduction. A week later, class will convene at the Gardens to study the content in-depth with plants in cultivated and wild settings.

Rain date: Thursday, September 9, 2021.
