This report covers conditions and observations made on Monday, February 9, 2015.

The first two of this report’s photos for the northern region provide something of a before-and-after view of the same Aldrich and Fritz planting west of Orland in Glenn County. (The Aldrich is the taller tree.) The first shot, taken on February 6, shows the orchard as the bloom was just beginning, while the second shot, taken on February 9, shows the very rapid progression that observers have noted in the past two days. Confirming the rapid development, our final image shows a Fritz and Nonpareil planting in the Williams area of Colusa County with a significant proportion of its flowers now available for pollination.

Partly cloudy skies and mild temperatures graced the Sacramento Valley on Monday, providing strong support for the rapidly developing bloom. Morning low temperatures were reported in the low 50’s while daytime highs reached into the mid 60’s. Scattered showers were reported in the southern areas of the region as the clouds built in intensity, with trace amounts to a few hundredths of an inch of precipitation reported. Observers noted that the bees were able to put in 8 hours of very good activity in the northern areas of the region and 5 to 6 hours of good activity in between shower events farther to the south.

As may be seen in the photos accompanying today’s report, the bloom has made very rapid progression over the past few days, as the comparatively warm temperatures the region has experienced have conspired to push bud development strongly ahead. With the exception of the late-blooming Padre, all varieties in the region are now displaying a measurable percentage of their flowers for pollination. The early-blooming Sonora continues to lead the Nonpareil, as do the California type varieties, as well as the Peerless and Monterey. While observers are reporting that the Carmel is generally trailing the Nonpareil, this important pollenizer variety is now also moving into bloom and is exhibiting sufficient overlap with its associated Nonpareil.

As may be seen in today’s third photo, growers who were able to enter their orchards have begun sending equipment into the fields to begin disease preventive treatments. Others with more poorly drained soils are being forced to wait for better conditions to initiate treatments to their disease susceptible plantings, or call on aircraft to complete the job. Observers have noted that many growers were opting to delay treatments until later in the bloom period, due to the rapid progression of bud development.
