Pear Branchless multi-leader

A good knowledge of how pear trees grow and fruit, and how they differ from apple trees, is essential for managing a branchless multi-leader pear orchard. The branchless multi-leader tree is a good example of a controlled canopy with good distribution of sunlight. This poses new challenges for orchardists, hence the need for a manual that complements our popular manual: pear on Open Tatura.

Since a picture is worth a thousand words, we have illustrated this manual with many photos and drawings, as we have with our other manuals.
This manual contains important aspects of pear behaviour, and shows you step-by-step how to develop and train the branchless multi-leader pear tree.
The branchless multi-leader pear tree is a relatively new training system in Australia and the manual will be progressively updated.
