Pruning Blueberry for Growth, Yield and Quality

This course will provide home gardeners and small farmers with information needed to prune blueberry plants from establishment through maturity. Discussion of the types of blueberries grown and adaptation throughout North America will ensure students throughout the USA and Canada use appropriate techniques for their region.

This module includes pruning methods and time of pruning for northern highbush cultivars grown in colder regions and temperate areas, southern highbush cultivars grown in areas with warm summers, and rabbiteye cultivars.

The impact of pruning on yield and quality is presented and discussed. Pruning young plants during the establishment years, producing fruit but also ensuring good bush development, as well as pruning mature plants for sustainable production are critical to success.

What You'll Learn

In this course, narrated lectures with photos and videos will address the learning outcomes, including an understanding of:

  1. Types of blueberries grown and regional adaptation
  2. The basics of plant growth, understanding wood age and terms used
  3. Pruning principles to address why pruning is important
  4. Pruning techniques and best time to prune
  5. How to choose the best fruiting wood when pruning
  6. Pruning from plant establishment to maturity
  7. Pruning techniques for mature plants
  8. How to prune stressed plants with poor growth
  9. How to fix poorly-pruned plants and how to prune after transplanting an established plant

How this Course Works

Although there are lessons that may apply more broadly, this course is intended primarily for a North American audience. It will be especially relevant for home gardeners and small farmers.

In this self-paced online blueberry course, you will navigate 2.5 hours of video in several lectures.

You will have access to the course and the materials for one year after you enroll.
