Course description

Learn and practice correct pruning techniques for trees and shrubs. Winter is a great time to prune. Bare branches make it easier to assess what needs to stay and what should be removed. Winter pruning also encourages proper spring growth.

Get started at home with self-paced online materials, which will cover key principles, techniques, and vocabulary with interactive elearning modules and videos. Then get hands-on practice in the field with a trained horticulturist on the grounds of The Morton Arboretum.

How Online Classes Work:

  • To access the online materials, you will log into TreeLearning, the Arboretum’s online learning portal. Instructions for accessing TreeLearning will be sent to registrants on the day the course begins. You have access to the online course materials for 60 days.
  • Complete self-paced e-learning modules with reading material, short videos, interactive activities, and quizzes to check your understanding.
  • The self-guided portion will take approximately 60 minutes. It does not need to be completed in one sitting, but you must complete it before your in-person class session.

Covid-19 Safety:

  • If you are unwell, or have been in contact with someone who is unwell in the last two weeks, you must stay home. A full refund will be issued on request.
  • Participants must bring face masks. Face masks are required while indoors. Face masks are also required outdoors when social distancing is not possible.
  • Maintain a distance of six feet from others whenever possible.
  • For more information on the Arboretum’s guidelines, please watch the video at https://www.mortonarb.org/visit-explore/plan-visit/know-you-go-visit-information.
