June Plant Report from Our Arborist Representative

“Our report includes up-to-date disease and insect pest reports for northeastern Illinois. You’ll also find a table of accumulated growing degree days (GDD) throughout Illinois, precipitation, and plant phenology indicators to help predict pest emergence. Arboretum staff and volunteers will be scouting for insects and diseases throughout the season. We will also be including information about other pest and disease problems based on samples brought into The Arboretum’s Plant Clinic.”
