  • Thursday, April 14, 2:00 pm – Garden Club of the Back Bay April Meeting – Trees from Seed: Conservation, Biology, and Ecology

    Sean Halloran, Plant Propagator at The Arnold Arboretum of Harvard University, will speak to us about Tree Propagation. Sean will start off with a brief overview of the plant conservation efforts at the Arnold Arboretum, and how plant conservation fits into every part of the Arnold’s mission.  He will then cover the basics of seed biology, and how seed biology and plant sexuality guide decisions about conservation and propagation. Sean will conclude by covering the many roles an urban tree may play, while highlighting a few underutilized native trees and shrubs. Questions are welcome throughout, with more opportunity for discussion at the conclusion of the talk.

    Sean Halloran received a Bachelor’s in Horticulture and a Master’s degree in Plant & Environmental Science from Clemson University where he focused on nutrient media in tissue culture propagation. His professional background includes private residential horticulture, greenhouse and nursery production, plant nutrient management in soil-less media, and temperate woody plant propagation and conservation. As the Arnold Arboretum’s Plant Propagator, Sean continues a 150-year tradition of growing woody temperate species from seed, cuttings, grafts, layers, and more; as well as being given the honor to travel and wild collect plants for the Arnold Arboretum.

Learn basic principles of grafting with an overview of different types of dormant-season grafts. Arnold Arboretum propagator Sean Halloran will provide step-by-step instructions so that you can practice both cleft and side veneer grafts using apple root stock. Simple after-care will be required until planting out in springtime. Registrants will need to sign an Assumption of Risk and Release in order to participate in this class.
