Need to nurture? Then join longtime Arnold Arboretum propagator Jack Alexander at the Dana Greenhouse at the Arboretum on two Saturdays, October 29 and November 5, from 9 – 4, to learn basic information and techniques for propagating most woody plants. Session One includes a lecture and workshop on seed propagation and construction of a propagation case. Session Two will be a lecture and workshop on hardwood cuttings. You will leave class with numerous cuttings and seeds to care for. To participate, you must sign an Assumption of Risk and Release in order to practice the techniques taught in class. Bring a lunch and beverage. If you own hand pruners, bring them to class. A sharp knife and an apron may also be helpful. You will be collecting propagules from the Arboretum grounds on both afternoons regardless of weather, so dress accordingly and wear comfortable shoes. Fee $180 member, $240 nonmember.
