    The Frelinghuysen Pinetum – Past, Present and Future

    Hear the fascinating story of how a summer home and estate built during Morristown’s Gilded Age became an Arboretum whose collection of conifers is now recognized as a Reference Garden by the American Conifer Society. Bruce Crawford will talk about the development of the Pinetum and some of the significant older conifer specimens, as well as some of the newest dwarf conifers in the collection donated by Frank and Joan Goodhart.

    10:45 AM – Beth Brantley, Bartlett Tree Research Laboratories

    The Conifer Conundrum

    Climate change, cultural conditions and pests and pathogens present challenges for many coniferous species. In her presentation, Beth Brantley will review species in decline, health issues and opportunities for alternative conifer species. Pests, pathogens, abiotic disorders and cultural challenges will be featured, with suggestions for managing these problems or avoiding them with more resistant conifer species.

    11:30 AM – Jean Epiphan, Rutgers Cooperative Extension Agent, Morris County

    Creating a Woodland Garden with Indigenous Plants and Vertical Structure

    Woodland gardens can be challenging to create and manage as they are inherently different from conventional garden beds and borders. Jean Epiphan will discuss how to use understory plants and shrubs, as well as natural mulches to restore soil health and native plant communities. She will offer suggestions on how to incorporate conifers at all levels of the three-dimensional landscape.
