The Lorette system of pruning

It is an early work about 1900; but was first publicly printed in 1925. Louis Lorette; who was an arborist and the curator and professor of an agricultural school in Wagnonville, France, developed a system of pruning fruit trees that involves summer pruning only. It maximizes fruit production in the orchard through an espalier system. He worked mainly with pear trees, but the system is appropriate for spur- bearing fruit trees of any type.

There have been a few revisions since the 1925 printing.
