The Science Behind "Leave the Leaves"

Summary

"Leave the leaves" has become an increasingly common mantra each fall. However, until recently little to no scientific research had been done to quantify impacts of leaving your leaves in a typical suburban yard. We discuss the results of that research and actionable steps that you can take in your own yard.

Today's guest
