This five-hour class at the Washington Park Arboretum will mix lectures and field demonstrations. Bess Bronstein will discuss up-to-date standards, best management practices, and the reasoning behind them for all methods of planting and transplanting. UW Botanic Gardens staff will demonstrate how to ball and burlap in our poor glacial till soils as well as transplant bare-root and container-grown trees. We will include a demonstration of our air-spade, showing root crown excavation and bare-rooting techniques in difficult situations.
