Grab a friend and join the Friends of The Frelinghuysen Arboretum on Wednesday, September 17th for a trip to Longwood Gardens in Kennett Square, PA. Let us take the stress out of driving so you can put your energy into exploring the beauty that Longwood has to offer.
September is a glorious time to visit this famous garden which was originally purchased by Pierre S. du Pont in 1906 in order to save the trees from being logged.
Since its opening in 1921 many additions and improvements have been made, including, in November 2024, a new Conservatory featuring interior Mediterranean-inspired gardens set amid pools, canals, and fountains. Other new additions include an outdoor Bonsai Courtyard and a preserved and expanded Orchid House.
More areas to visit include the Italian Water Garden, the 5-acre Main Fountain Garden with shows at 1:15 PM, and 3:15 PM, the Meadow Garden, Chimes Tower and Waterfall, and the Eye of Water. Click here for a downloadable map of the gardens: https://longwoodgardens.org/media/44725/download?inline
Self guided tours allow you to explore at your own pace and linger where you wish.
Lunch at the Cafe, Beer Garden, or the 1906 Restaurant to satisfy your hunger. Reservations are recommended at 1906, as it is first come-first served otherwise. Please note that although the restaurant is open until 4:30 PM, the last reservation available is at 3:30 PM. Reservations are not available for the Cafe and Beer Garden.

Hazardous Tree Identification

Hazardous trees pose a double danger, they are tough to recognize and they can be costly, even deadly, if not managed before an avoidable accident happens. In this presentation, Ted will walk you through the step-by-step process of identifying, assessing and developing a hazard mitigation plan to assist you in maintaining a healthy tree resource.

11:00 AM – Jean Epiphan
Tree Care Fundamentals to Reduce Stress and Disease

Jean Epiphan will discuss important foundational steps to reduce transplant shock and establishment stress to improve tree health and longevity. Topics include key aspects of site selection, soil types and amendments, proper planting of B&B and container stock, root collar excavations, ideal mulch options, bed size, structural pruning, best watering options, and reducing impacts of lawn trimming. Cultural practices can go a long way to support tree health and avoid the use of pesticides.
Jean Epiphan is an Agriculture & Natural Resources Agent/Assistant Professor at Rutgers Cooperative Extension of Morris County. She is a New Jersey Licensed Tree Expert and ISA Certified Arborist and certified in wetland delineation, wetland construction, and ecological restoration.

Jean has worked in the landscape & tree care industry as a grounds manager, tree curator, landscape designer, and an arboricultural and ecological consultant. In her current role she focuses on improving environmental sustainability and ecological health in ornamental horticulture as well as landscape management and conservation practices.
12:00 Noon – Lunch – Assorted Sandwiches
1:00 PM – Kevin Chase
Current and Future Threats to Urban Trees and Shrubs

The focus of this talk will be on two recently established pests – box tree moth and beech leaf disease. Both pests are plant killers and are spreading rapidly. The biology, spread and management of each pest and disease will be discussed. Additionally, we will discuss a new canker and leaf spot affecting American and European hornbeam.
Kevin conducts entomological research on a variety of tree and shrub insect pests across North America, the United Kingdom and Ireland. Some of the major insect groups Kevin works with are scale insects, invasive caterpillars, bark beetles and wood boring insects. Kevin is also involved in trialing biological control agents and safer products for both human applicators and non-target insects.
Based in Harrisburg, Pennsylvania, Kevin’s applied research focuses on integrated pest management of ornamental pests on the urban landscape. He researches how biological control can be used in plant health care programs as well as how to manage new invasive insect pests as they move across the globe. Kevin holds a Master of Science in Forest Entomology from Mississippi State University, a Doctor of Philosophy in Ecology from University of Canterbury, New Zealand and a Postdoctoral Research Associate in Forest Entomology from the University of Minnesota.
