Proceedings Overview

The IPPS Combined Proceedings

A unique benefit IPPS members enjoy is free online access to the Combined Proceedings, a vast library of horticultural knowledge!

The IPPS Proceedings are a collection of all the papers presented at the IPPS conferences held annually in each of the Regions, since 1951. There are now 69 volumes of professionally edited papers available online.

Conference presentations are also available online as un-edited PowerPoint files. Selected presentations are available as online videos.


Reprinting and quotations from the Combined Proceedings International Plant Propagators' Society papers published are permitted only on the condition that full credit is given to both the Combined Proceedings International Plant Propagators' Society and written approval is obtained from the author(s). In addition, the volume, pagination, and date of publication must be indicated.


The published Proceedings represent the view of the authors or persons to whom they are credited and are not necessarily those of the Society. The publication of research or other types of information by the Society does not constitute a recommendation or endorsement of products or procedures involved; for general use, label recommendations, and directions must be followed.
