Format: IN-PERSON
Instructor: Polly Samland
Learn more about the Pruning Workshop
This half-day workshop will introduce you to the fundamentals of pruning and aims to provide you with basic skills to confidently approach pruning in your own landscape. We begin with how to form pruning strategies, including choosing and maintaining equipment and understanding plant growth and timing. Pruning cuts and techniques will be discussed, demonstrated, and practiced together outdoors.
Fee: $65 (plus HST) per person if booked before the early bird deadline of Monday, March 10, 2025. After the early bird deadline the fee is $75 (plus HST)
Virtual Composting for Gardeners - Composting Piles, Bins and Drums
Tuesday, March 18, 2025
7 - 8 PM
Format: Online via Zoom
Guest Instructor: Robert Pavlis
Learn more about our Composting Piles, Bins and Drums Program
The previous workshop provided information about the composting process. This workshop is more hands on and looks at various methods for completing both hot and cold composting. Hot composting is the traditional method using one or more bins. This is a great system that makes faster compost, but it is impractical for smaller gardens. Various plastic bins and drums are more suitable there. We’ll have a look at various commercial and DIY systems.
At the end of this course you will be able to select the right composting system that meets your requirements and you will know how to start the process, care for it, and what to do with the finished compost.
If you are going to take this course it is a good idea to also take Introduction to Composting for Gardeners.
Fee: $10 (plus HST) per person.

Virtual Composting for Gardeners - Vermicomposting
Tuesday, March 25, 2025
7 - 8 PM
Format: Online via Zoom
Guest Instructor: Robert Pavlis
Learn more about our Vermicomposting Program
Vermicomposting is a way of using earth worms to compost organic material. One benefit of this method is that it can be done in the home using special bins that require a very small space.
The course will introduce you to the equipment needed including some inexpensive DIY options. It will help you select the right kind of worms and show you how to maintain them to keep them healthy. We’ll review ways of harvesting the vermicasts – the worm poop – and explain how it should be treated for best results in the garden.
At the end of this course you will know the basics of taking care of your new pets and how to resolve any problems you might have.
If you are going to take this course it is a good idea to also take Introduction to Composting for Gardeners.
Fee: $10 (plus HST) per person.

Winter Storytelling Series

Instructor: Cara Loft
Learn more about the Winter Storytelling Series
Mohawk Creation Story - Friday, January 31, 2025
Story of the Haudenosaunee Confederacy - Friday, February 28, 2025
Story of How Maple was Gifted to People - Friday, March 28, 2025
Story of the Three Sisters - Friday, April 25, 2025
Shé:kon Sewakwé:kon, Skén:nen! Hello Everyone, Peace be with you! My name is Cara Loft and I am a Haudenosaunee Woman who is a staff member at the Office of Teaching and Learning at the University of Guelph. I am excited to invite you to come spend time on the Land to listen to several traditional Kanien:ke (Mohawk) stories. During the long Winter months, when Mother Earth is asleep beneath her blanket of white, we share stories with one another and come together for community. The Kanien:ke culture is traditionally an oral language. Our history, teachings and other important information is conveyed through the practice of storytelling. For this event, we will begin, and end, in a Goodway; with smudge and a traditional handdrum song. We will then make tea for ourselves to stay warm and proceed to walk designated (clear) trails to re-connect with the Land. As we walk, I will share story in a Goodway. If the weather is inclement, and the trails are not clear, then we will gather inside for storytelling. If you are interested in learning more about the Kanien:ke culture, and re-connecting with the Land, please come share space with us! Please make sure to dress appropriately for the weather and bring a reusable mug for tea! Nia:wen Kowa! Thank you! – Cara
Dress for the weather as we will be outside unless the weather is inclement, then we will move indoors.
What to expect: There will be some traditional practices such as smudging, drumming and singing. So come with an open mind and heart. It is encouraged to bring a travel mug, to have some tea.
This program is FREE. We do ask that if you register and can't make it that you notify us so that someone else can have your spot as space is limited. You can register for one or more of the sessions.

Virtual Bird Sounds Series

12:00 Noon - 1:00 PM
Format: Online on Zoom
Instructor: Chris Earley, Arboretum Interpretive Biologist
Learn more about our Virtual Bird Song Programs
Into birding but the songs have you stumped? Whether you are new to learning bird sounds or you want a good refresher, this course is for you. Join Chris Earley, Arboretum Interpretive Biologist and author of 5 bird field guides, for a series of eight virtual noon-hour lectures that cover over 150 bird species! We will focus on songs and some common, distinctive calls and will apply different methods to remember them. Each course will start with a short intro topic about birding by ear before we dive into the bird species. Learn how to make your own calls, read a sonogram, make up your own memorable bird song sayings, and more! Each class will finish with a 10-15 minute discussion period so you can ask all your bird-related questions. See the descriptions below to find out which bird groups are covered in each class. All eight programs cost of $70 (plus tax) - that's less than $10 per program! This fund-raising initiative will help support other Arboretum educational programs.
Fee: $70.00 + H.S.T. This event will take place on Zoom. The list of topics with the presentation date is listed below. If you miss any of the programs, each one is recorded and the recording will be sent to you the next day. The recordings will be available for one month after the last program.
Owls and Wetland Birds - Day 1 - Monday, March 17, 12 noon – 1:00 PM
Whooooooo was that? Owls always grab our nightly attention but many wetland birds are also evening singers. We will cover a selection of rails, coots, bitterns, loons, grebes, and more. And don't forget a couple of glorious goatsuckers (whip-poor-wills and nighthawks)! This course will include teaching you how to speak "owl."
Blackbirds and Hawks - Day 2 - Wednesday, March 19, 12 noon – 1:00 PM
These two groups include some early migrants and now is the time we get to see them after a long absence! We will cover the whole blackbird family including meadowlarks, bobolinks, and orioles. We will also study some raptor calls so you can figure out who might be flying through or maybe nesting in your local forest.
Warblers I - Phrasers and Buzzers - Day 3 - Monday, March 24, 12 noon – 1:00 PM
Knowing warbler song is a key element for finding these tiny trinkets of the treetops. The males will even sing during migration so knowing their voices is important. In this course we will start with the species that sing distinctive phrases or use a buzzy texture in their songs.
Warblers II - Trillers and Thrillers - Day 4 - Wednesday, March 26, 12 noon – 1:00 PM
So, this time things might be a bit more, um, difficult. Trilling birds are tricky but we will go through them and study the differences in these similar songs. We will also cover some other warblers that are a bit more musical and easier to figure out!
Sparrows - Day 5 - Monday, March 31, 12 noon – 1:00 PM
They may be a lot duller to look at than warblers but most sparrows are much better singers! Sometimes it is easier to tell them apart by song than by sight. We will study who says "Home Sweet, Canada, Canada, Canada", "I gotta go wee wee now!" and "Won't you come sit down besiiiiiide meeeee?"
Finches and Thrushes - Day 6 - Wednesday, April 2, 12 noon – 1:00 PM
Finches, including grosbeaks, redpolls, and crossbills, can be sparrow-like but are even better songsters. But some of them sound the same so we will figure out ways to tell them apart. Their call notes can be important during bird surveys so we will cover some of them, too. Thrushes have lovely voices and one was once voted as the best singing bird in North America! Find out which one at this workshop.
Woodpeckers and Flycatchers - Day 7 - Monday, April 7, 12 noon – 1:00 PM
Sometimes you have to know mechanical sounds to figure out a nearby territorial bird - woodpecker drumming is a prime example. They also make some distinctive calls. And speaking of distinctive, some flycatchers can only really be identified by their songs, not by sight! We will listen to these and get a handle on this confusing group.
Wrens and Friends - Day 8 - Monday, April 9, 12 noon – 1:00 PM
We will finish off with a hodge podge of species such as wrens, vireos, jays, nuthatches, kinglets, and more! Many of these live in forest habitats and could all be singing or calling at the same time so learning to differentiate them is an important skill. Are you ready for the challenge?
