Hands-on tree care, pruning & mulching workshop Saturday, September 25, 2021

September 25 @ 8:00 am - 12:00 pm


Starts at 8am
Stay as long as you can or want.
We plan to be wrapped up with the supervised pruning in the neighborhood by noon

Cost: $5 suggested donation, though no one will be turned away due to lack of funds.

Where: the Dunbar Garden space (NW corner of 11th Ave and University Blvd). Tucson, Arizona

Open to all. Learn how you can organize similar Neighborhood Forester efforts in your neighborhood.

After demonstration we will move to various parts of the neighborhood to get supervised hands-on experience as we help prune native food-bearing trees and shrubs in our neighborhood’s public rights-of-way.

This is an incredible learning opportunity as every six months we revisit and rework areas pruned so we see the effect of our good work and mistakes, thereby enabling us to improve and evolve with the expert guidance from certified arborist Aleck MacKinnon.

We’ll also cover how to prune to keep trees below power lines out of conflict with the utility lines.

Professionals can get continued education credits for the workshop from Aleck.

Certified arborist, and owner of the Pedaling Arborist, Aleck McKinnon teaching a pruning & mulching workshop. After the demonstration portion of the workshop, Aleck and other instructors guide the students as they practice what they are learning by pruning and mulching a section of the neighborhood’s forest in need of such work.

Instructors: certified arborist Aleck MacKinnon of the Pedaling Arborist, assisted by Brad Lancaster of the Dunbar/Spring Neighborhood Foresters.

Bring pruning tools if you have them. We’ll provide for those that don’t.

Also bring water and snacks, and dress (sun hat, gloves, etc.) to be working outdoors in the sun.

Please prune to maintain access to our neighborhood forests and their public paths
All public rights-of-ways adjoining properties must maintain a continuous clear walkway area a minimum 5 feet wide and 7 feet tall to make our neighborhood walkways and forests accessible for all.

Public path with obstacles pre-pruning
Public path cleared post-pruning

Recycle your prunings & their fertility

Cutting up prunings to 6-inch or shorter pieces to use as a soil-sheltering, water-conserving, fertility-building mulch within a water-harvesting basin.
