Arboriculture starts in the nursery. The importance of young tree structure both above and below ground has lead to the development of the “Guideline Specifications for Nursery Tree Quality” and the "Strategies for Producing High Quality Container Root Systems, Trunks, and Crowns." The documents represents an effort to combine industry input with the most recent, tested scientific practices to address nursery tree quality and production. Please consider reviewing the documents and distributing them to anyone that may benefit from the information.

The “Guideline Specifications for Nursery Tree Quality” provides specifications for selecting and specifying quality nursery trees in California, with a focus on container stock. Key traits of nursery trees are identified and described to provide growers and buyers with the information they need to distinguish good-quality stock from poor-quality stock.

The "Strategies for Producing High Quality Container Root Systems, Trunks, and Crowns." This document presents strategies to assist growers in producing trees that conform to the Guideline Specifications for Nursery Tree Quality. The strategies are based on most-recently-published and ongoing research, combined with the knowledge, skills, and know-how of both the practitioner and researcher, to produce high-quality root systems, trunks, and crowns . As research progresses and new strategies are developed, this document will be revised to incorporate state-of-the-art information.
