​​2026 Summer Stewardship Events
Information for Summer Events
Starting in June, stewardship events will be hosted to maintain and monitor newly planted trees and wildflowers. Under the guidance of our volunteer lead, you will help us water, mulch or weed in natural areas. These events will be held from June to September on most Wednesday afternoons (4:30 PM) and Saturday mornings (9:00 AM). Locations will be in Markham and will change from event to event. These are small drop-in events and no registration is required except for groups over 5 people. If you have a group of five or more, please contact Patrick at vchair@10000trees.com so that we can confirm if the event will fit your group. High school students can bring their volunteer forms for sign-off.
​
More details for each event (location, time, equipment to bring) will be provided two weeks before each event. ​

What to expect at a 10,000 Trees Event?
-
All events are free and open to the public. Feel free to invite your friends and family and attend as a group!
-
Events usually last 3 hours. If you are only able to make part of an event, we encourage you to sign up for another event and to allow others the opportunity to attend instead.
-
Tickets are limited based on the size of the planting area and the number of trees we have available.
-
We only plant native trees! Native trees support native wildlife. All trees are native to southern Ontario and are selected to mimic a native forest habitat.
-
No experience is required! A 10,000 Trees volunteer will demonstrate proper tree planting technique at the start of the event.
-
Bring your own shovel and a 5 gallon bucket. We will have extra shovels if you need one.
-
Plant as many trees as you like. But one well-planted tree will always be better than 10 poorly planted trees. ​​​​​
