Registration is now open

Understanding the fundamentals of tree biology is essential to making sound orchard management and business decisions in the tree fruit and nut industry.  However, access to educational courses on basic fruit and nut tree biology, and how it relates to agronomic practices, is limited. Our course incorporates lecture, lab exercises, and field demonstrations to provide information on all aspects of basic plant biology and the relationship between plant biology and nuts and fruit orchard management.

Our course includes nine full days of instruction. The first five days will be held on the UC Davis campus and include lecture, laboratory exercises, and field demonstrations. The following week we will embark upon a four-day field trip throughout fruit and nut tree growing regions of Northern and Central California. Click here to register for the course
