SUMMARY:Seed Propagation at the Arboretum
DESCRIPTION:Rescheduled from October 5 due to construction. \n\n\n\nThis is a members-only program. Not a member? Click here to join! \n\n\n\nMany of us assume that growing plants from seed is as simple as opening a seed packet and sticking them in the dirt\, but many of the trees and shrubs in the Arboretum’s collections require a complicated process of stratification\, maceration\, and dormancy breaking before they will sprout. Join Arboretum Propagator Sarah Shank for a workshop on growing these plants from seed and get a chance to try your own hand at germinating seed from Arboretum trees and shrubs. \n\n\n\nThe class will begin with a presentation on the biology of seed dormancy and germination\, and then we will move into the hands-on portion where participants get experience preparing seeds from fruits and dry capsules\, scarifying seeds with different dormancy types\, and finally sowing some seeds to take home. We will round off the experience with a brief tour of the seed treatment facilities and seedling greenhouse. \n\n\n\nAll participants will go home with a tray of seeds they planted. We will be focusing on plants that can easily be grown in a front or backyard\, so you don’t need to worry about finding a place for a 100-foot-tall tree! \n\n\n\nAccessibility: This program takes place indoors in the wheelchair-accessible DGH classroom and outdoors on mowed grass. \n\n\n\nAudience: This members-only program is geared towards adults. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.

SUMMARY:Chainsaw Safety and Maintenance
DESCRIPTION:This program has been cancelled. \n\n\n\nJoin Head Arborist John Del Rosso for a class on chainsaw safety and maintenance. Designed for professionals and gardeners with some chainsaw experience\, you will learn how to best maintain your chainsaw\, make effective felling cuts and tension cuts\, use proper PPE\, and develop safe work habits. \n\n\n\nParticipants will not operate chainsaws during this class\, instead learning through instruction and demonstration. You are encouraged to bring your own PPE (eye protection and ear protection) for the demonstrations. You are welcome to bring your own chainsaw if you have specific questions about it for the instructor\, but chainsaws will be placed outside of the classroom during the class. \n\n\n\nThe class will begin in the Hunnewell Lecture Hall and will move out to the lawn for demonstrations. \n\n\n\nAccessibility: This program takes place indoors and on flat\, mowed grass outside. \n\n\n\nAudience: This program is for ages 18+. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.

SUMMARY:The Cosmic Tree: A Universal Symbol of Life: Ginkgoes & Conifers
DESCRIPTION:Cosmologies are ways of understanding the nature of the universe\, of experiencing the world in all its variations including the visible and the invisible. Over millennia trees have served as the mythological archetype of the world’s axis (axis mundi)\, the pole through the earth’s center which connects the worlds above and below. Within a cosmic-magical model of the world  (imago mundi)\, trees also evolved in various cultures to possess innate spiritual powers or as conduits for communication with the holy or sacred. \n\n\n\nDocent Katrina Scott will lead this interactive tour with stops for moments to reflect on specific trees and the stories associated with them. Were they revered or feared?  A home for deities or tricksters?  We will begin at the Walter Street Gate to visit the oldest ginkgoes at the Arboretum\, then head up the Conifer Path and diverge to walk\, rest\, and reflect among various conifers\, eventually ending by the yews near Bussey Brook and Hemlock Hill Road.  \n\n\n\nAccessibility: This walk will include woodchip and gravel paths. Please wear long pants and closed toe shoes and bring a cloth/towel/mat for sitting/lying down. \n\n\n\nAudience: This program is geared towards adults. \n\n\n\nWeather Policy: Tours may be canceled in cases of the following weather conditions: severe wind\, snow\, ice\, thunder or lightning events; temperatures over 90 degrees; and temperatures below 20 degrees or due to other weather events at the discretion of Arboretum staff. In the case of cancelation\, you will be contacted by Arboretum staff no later than 2 hours before the start of the event. If you have questions about the status of a program\, please email or call the Visitor Center at (617) 384-5209 between 10:00am and 4:00pm.

SUMMARY:Mushroom Hunt
DESCRIPTION:Hundreds of mushrooms hide beneath the Arboretum’s canopies\, silently blossoming into unique forms then withering away again just as quickly. Join local mushroom enthusiast Maria Pinto to search for these fascinating organisms on the Arboretum grounds\, both edible and poisonous alike. Along the way you will learn what mushrooms to look for in different habitats and seasons\, how they move through ecosystems\, and what the Arboretum’s unique collections affect what mushrooms you might find here. \n\n\n\nAccessibility: Participants will need to navigate woodchip\, gravel\, and dirt paths\, and climb moderate hills (Hemlock Hill\, specifically). \n\n\n\nAudience: This program is geared towards adults. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.

SUMMARY:Tree Mob: The Oldest Tree in the Arboretum
DESCRIPTION:This is a members-only program. Not a member? Click here to join. \n\n\n\nLong before this landscape had ever dreamed of becoming an Arboretum\, a white oak grew quietly on the slopes of Peters Hill. Years passed and Arboretum staff eventually incorporated this very old tree into our official collections\, making it possibly the oldest accessioned tree in the landscape. Join Assistant Curator Miles Sax for a Tree Mob to learn about this oak\, what the landscape looked like before it was an Arboretum\, the science of tree age\, and how the Arboretum manages those trees that we never chose to plant but which are a treasured part of our collections nonetheless. \n\n\n\nAccessibility: This program involves walking over mulch and paved paths and up a moderate hill. \n\n\n\nAudience: This program is geared towards adults. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.

SUMMARY:Built to Withstand: How Plants Resist Wind and Weight
DESCRIPTION:How do trees\, bamboo\, marsh grass stems and cattail leaves stand so tall?

SUMMARY:Reading the Forested Landscape
DESCRIPTION:The forest is a constantly changing landscape where tree species dominate and then fade away\, to be replaced by other species in the ongoing process of succession.
