Advisor Retirement

I am retiring on July 1st after nearly 38 years working for UC Cooperative Extension and over 36 years as an Orchard and Environmental Horticulture (EH) Advisor in Sutter-Yuba Counties. What an honor to work with all of you growers, PCAs, and others in the Ag industry, and such a privilege to collaborate with so many talented UC colleagues solving challenging problems together.

These nuts were full size with the shell beginning to harden. Cutting open an immediately dropped nut, you could see darkening of the inside watery kernel material. Several possible causes are explored in this article.
