Classes & Workshops


PlantAmnesty instructors teach pruning techniques through our Master Pruner Program. A series of twelve 2-hour classes and three hands-on workshops provides students with a solid base in the science and practice of selective pruning. Our instructors are professionals in the field and bring years of personal experience to their classes.

Our classes are open to professionals and to the general public and may be taken individually for specific interests.

The nine core classes include:

  • Tree Pruning I and II   note: Tree Pruning I should be taken before Tree Pruning II or Fruit Trees.
  • Shrubs I, II, and III
  • Fruit Trees
  • Art or Atrocity
  • How to Prune and Renovate the Overgrown Garden
  • Rehabilitative Pruning

An additional three specialty classes from our offering can be selected for a total of twelve classes.

Our core classes and two specialty classes will be offered through our online Sunday morning schedule. Selected classes, which may include some of the most popular core classes, will be offered in person, schedule yet to be determined. Additionally, new classes under development will be offered in person or online outside of our Sunday morning schedule. Recordings of online classes are available to view for two weeks after the class date.  There are no provisions for viewing the recordings outside the established schedule.

Please note that if you are registering multiple students for in person or online classes, we encourage you to enter their names and email addresses during registration, ensuring that they will receive class handouts and a Zoom reminder sent directly to their email addresses for online classes. For in person classes, we will need to know attendee names for registration check-in.
