Growing the Valley

UCCE Advisors Katherine Jarvis-Shean (Yolo-Solano-Sacramento Counties), Roger Duncan (Stanislaus County), and Joe Connell (Emeritus Butte County) come together to discuss current available almond rootstocks and the importance of selecting rootstock for growers’ orchard-specific challenges.

Video from the Almond Board of California showcases the Boron tolerance rootstock trial in Yolo County. Additional information on almond rootstock trials conducted in Yolo and Butte counties can be found on SacValleyOrchards, as well as an overview of alternative rootstocks on SJV Tree and Vine.

This episode was originally intended to be part of the climate change series, but ended up being more appropriate as a stand alone episode. Phoebe and Mae Culumber (UCCE Fresno County) discuss the importance of carbon in soil quality, as well as explains some research she’s doing on the role of nitrogen in whole orchard recycling.

Janine Hasey (UC ANR Cooperative Extension Farm Advisor Emerita) discusses sudden freeze events, their effects on walnut, and necessary steps to mitigate future freeze damage.

We encourage you to take our survey on walnut freeze, which is available until Dec 1, 2021.

The purpose of this survey is to gain greater understanding of freeze damage in walnuts. For the purposes of this survey, freeze damage is defined as damage observed in spring yet incurred during the previous fall from cold temperatures below 32 degrees Fahrenheit.

The results from this survey may be used to develop further surveys and research projects regarding freeze damage in walnuts, and will be shared via peer-review publications, extension talks and articles, and/or conference presentations. No personal information will be shared.
