Landscapes that Save the World: The Importance of Biodiversity in the Garden
When it comes to landscapes, there is strength in diversity. All too often gardeners don’t spend enough time thinking about how important it is to promote a well-balanced ecosystem in their home landscape. This talk focuses on why it’s important to create biodiverse landscapes, and how we can achieve that goal in our own garden spaces. Topics will include “plant blindness”, attracting wildlife, pollinator gardens, building soil, managing turfgrass, importance of native plants and more!
