JUNE 15, 2022 YOUR NORTH COAST ORCHARD NOTES

In order to accommodate Delta harvest timing, I have scheduled a morning field meeting to view the 2013 NC-140 Orchard Systems Trial at Shadowbrook Farms in Hopland (Mendocino County) on JUNE 28, 10:00-NOON. The trial is in its 10th leaf and consists of 4 training systems, 3 spacings, and 3 rootstocks, totaling 36 separate combinations. There are also completely unpruned trees on two rootstocks and a separate trial comparing spread and unspread trees for the bi-axis training system.

 

The trial is one of three planted in 2013 in California (Bartlett), Hood River, Oregon (Anjou), and New York (Bosc). Only the CA and NY trials have survived. This is the final year of data collection, thus the occasion for a field viewing.
