Blue Diamond releases latest Crop Progress Report
This report covers conditions and observations made between Saturday March 18 and Sunday, April 2, 2023. The next scheduled report will be posted on Monday, May 1, 2023. In the event of any significant occurrences prior to that date, Blue Diamond’s site will be updated as soon as possible.
The report outlined the significant rains that the storm systems brought to the Valley, and the snowfall to the Sierra Nevada watershed area, all at record levels.

According to the report, the rainfall totals during the report period ranged from “just over .5 inch in the southern San Joaquin Valley to over 4.5 inches along the west side of the Sacramento Valley.”
The unseasonable weather conditions have created a challenge for the growers to evaluate crops and in turn, determine crop management plans.
“As shown in the photos accompanying this report, nutlets of all varieties have been differentiating in size, the normal process where those that were not fertilized during the bloom wither and fall from the tree. Of those that remain, observers are reporting two to three sizes splitting and breaking free of their jackets,” the report stated. “Experience has proven that the smallest of the sizes will be shed from the trees, a process that is normally well underway by the end of March. However, this year the cold temperatures have delayed the shedding process, making crop evaluations a bit more challenging. An interesting note this year is the number of ‘twin nutlets’ present in the developing crop. While visible in all varieties, the Independence variety in particular is displaying the greatest proportion. Experience indicates that these ‘twins’ will be shed from the trees in the coming weeks and very few will be retained to maturity.”
