NOTICE: Beginning November 1, 2012, for safety and esthetic reasons, the overgrown hemlock hedges along the Prospect St face of Marsh Hall and Marsh Botanical Garden will be gradually removed. The existing large trees will be interplanted with mixed Rhododendron and other Ericaceous species, along with Aquifoliaceae, as already exists at the entry walkway for Marsh Hall.
A subcommittee of Marsh Botanical Garden’s Steering Committee has recommended that this hedge be removed. Eastern Hemlock, also known as Canadian Hemlock (Tsuga canadensis) is subject to predation from armored hemlock scake and woolly adelgid. Without spraying or applying other pesticides the life span of these trees will be compromised. They are also planted under power lines making their full growth problematic.
