This report covers conditions and observations made on Tuesday, February 17, 2015.

Taken along the west side of the Sacramento Valley, today’s photos for the northern region provide a down-the-row-view of a Nonpareil and Winters planting, showing the more advanced leaf cover of the Winters, a close-up of the Sonora coming through their protective jackets and a shot of the Butte and Padre varieties in full bloom.

Excellent weather continues to support bloom in the Sacramento Valley. Early fog in the Williams area burned off by 10:30 and temperatures quickly rose from the low 40’s during the morning hours, reaching into the low 70’s by early afternoon. In the Chico area, temperatures ascended even faster due to the lack of fog. Winds stayed relatively light most of the day, making for another gorgeous day in the northern region. With bloom beginning to wind down in most cultivars, orchards continued to hum with bees. Observers noted that the bees put in 6 to 8 hours of very good activity.

Bloom has hit its overall peak in the northern region for most varieties. The early blooming Sonora has nearly shed all of its petals in the Chico area, and has a very small measurable proportion of its flowers available to the bees, while in the Williams area, farther to the south, the Sonora still has approximately 25% of its flowers open and available. Nonpareil plantings reached their peak condition in the northern area of the region a few days ago, while southern areas are nearing their peak bloom at this time. This pattern also exists for all other varieties, with the northern areas of the region running a few days ahead of plantings in the Yolo and Colusa County area

As shown in this report’s second photo, early blooming varieties are pushing leaves at a rapid rate. The Winters variety in particular, being a very early blooming type is becoming increasingly green with leaves as each day passes.
