Attendees will learn about soil structure/composition and analysis as well as topics such as pollinator hedgerows, principals of soil health, landscaping with native plants, permaculture, pest management without pesticides, diagnosing plant problems and rebuilding urban soils.   

A new feature this year will be the Hands on Soil session, repeating throughout the day, in the outside Learning Garden at PCC Rock Creek.
