UNH Cooperative Extension Workshops

Shrub disease and invasive insects in Peterborough? Learn all about it! 
UNH Cooperative Extension, Hillsborough County

In response to the recent discovery of boxwood blight in Peterborough, The NH Department of Agriculture Markets & Food and UNH Extension have put together a workshop to educate home gardeners, landscapers and property managers about this devastating disease, as well as the status of two important invasive insects, Asian Longhorned Beetle and Spotted Lanternfly. In this session, Emma Erler will present the signs and symptoms of boxwood blight, prevention measures and disease management. Morgan Dube will follow Emma and share the latest information on Asian Longhorned Beetle and Spotted Lanternfly, and how to report these pests if you find them in New Hampshire.
