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.
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.
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.
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.
