Tree University:  Akiva Silver's Trees of Power

April 29, 2021, 6:00 p.m. - 7:00 p.m.

Chadwick Arboretum invites you to kick-off our Arbor Day 2021 celebrations with us during this 1-hour webinar!  Come listen to Akiva Silver, author of the 2019 book, Trees of Power. Akiva will be speaking about his book and sharing some information he's learned about growing chestnut trees. Trees of Power explains how we can work with 10 arboreal allies, specifically focusing on propagation, planting, and individual species. Akiva is an enthusiastic tree grower with years of experience running his own commercial nursery. In this book he clearly explains the most important concepts necessary for success with perennial woody plants. 

This talk is for everyone who wants to connect with trees. It is for the survivalist, the gardener, the homesteader, the forager, the permaculturist, the environmentalist, the parent, the schoolteacher, the farmer, and anyone who feels a deep kinship with these magnificent beings.

Retirement of Chadwick Arboretum Director Mary Maloney

After 27 years of dedicated leadership, Mary Maloney is retiring from her role as Director of the CFAES Chadwick Arboretum & Learning Gardens. Mary’s last day at Chadwick was September 30th. During her time at the Chadwick Arboretum, Mary expanded the volunteer program, assisted in expanding the gardens to include the Learning Gardens, Green Roof, Cancer Survivors Plaza, and the Arboretum North site. She also assisted in the certification of Chadwick Arboretum, built partnerships, expanded tours and outreach, enhanced fundraising and events, and so much more. Mary has been a great mentor to many students and colleagues, and she will be missed.

Dewey Mann, Director of Waterman Agricultural and Natural Resources Laboratory will be appointed as Interim Director of Chadwick Arboretum & Learning Gardens. Pam Bennett will serve alongside Dewey as Interim Chadwick Arboretum Program Director. Pam is an Associate Professor who serves as Extension Educator in Clark County and as state Master Gardener Volunteer Program Director.

Chadwick Arboretum & Learning Gardens and its extensive, urban, green reserve of over 60 acres is an important asset of CFAES and the University. It is used throughout teaching, research and Extension mission areas. Therefore, Chadwick Arboretum will be moved into the larger CFAES Operations portfolio, under the direction of Associate Dean Graham Cochran, to better align and support this unit which serves many departments. Later this fall a transition team will be appointed (internal to CFAES) who will work with CFAES college leadership on strategic direction for Chadwick Arboretum and what is sought in a new director. CFAES will also engage University partners, the existing Chadwick Arboretum advisory committee, and volunteer base for input.

Annabelle The Preying Mantis Renovation

Artists Pat Belisle (green shirt), and Chris Saylor (gray shirt) who designed, built, and installed our 15’ sculpture of Annabelle the Praying Mantis updated her look with a fresh coat of paint and did cataract surgery on her by replacing her rusty eyes with shiny new ones!

Annabelle the Praying Mantis was installed in 2008 in our Lane Avenue Gardens specifically in the Phenology Research Garden. Her last cataract surgery was in 2012 prior to the American Public Gardens Association national meeting that was held in Columbus. Chadwick Arboretum was a host garden along with Franklin Park Conservatory and Dawes Arboretum.
