Spring is a great time to assess woody shrubs for shape, structure and winter damage. On Saturday, March 28, from 9 a.m. to 1 p.m., arborist Kieran Yaple will demonstrate how to renovate, rejuvenate and shape shrubs and small ornamental trees for structure, health and optimal growth. The class will cover viburnums, lilacs, witch hazel, deciduous azaleas, sweetshrubs, crabapples, and ornamental cherries. Participants should dress for the weather and bring pruners, work gloves and lunch. Some pruners, provided by BBG, will be available for use.

Kieran Yaple is a Massachusetts-certified arborist and an International Society of Arboriculture-certified arborist. He is also a Certified Tree Safety Professional and is pesticide-licensed in Massachusetts. He recently joined the board of directors of the Massachusetts Arborists Association.
