Northern California - March 5, 2013

This report covers conditions and observations made Monday, March 4, 2013.

Today’s photos for the northern region present the petal fall and jacket stage of the Sonora variety, showing its increasingly green leaf area in the Durham area of Butte County, followed by the dwindling bloom of the Nonpareil and Aldrich and the peak bloom of the Butte and Padre, both in the Williams area of Colusa County.

Weather conditions in the northern region provided for one more day of good opportunities for pollination before the arrival of a Pacific weather system forecast to pass over the state. Morning low temperatures were widely reported in the lower 40’s while daytime highs reached into the mid and upper 60’s. Observers reported that breezy conditions during the afternoon hours helped to scrub some petals from the trees and accelerate the degree of petal fall in many plantings. However, the light winds failed to significantly affect the bee’s efforts during the day and observers reported 8 hours of excellent activity in the orchards with a steady hum evident all day long.

The bloom in the northern region continues to run ahead of that in the San Joaquin Valley with all varieties now having some degree of their flowers in the petal fall stage. Sonora leads the region’s varieties, having the greatest amount of any variety in the jacket stage and smallest proportion of bloom remaining available for pollination. Peerless, which is marketed primarily as an in-shell nut follows the Sonora and leads the various California type varieties, which have just over a majority of their flowers open and viable as this time. Advanced examples of the Nonpareil are now moving into the petal fall and jacket stages with the viable proportion of their bloom declining steadily. Finally, late blooming Butte and Padre are now at or near their peak bloom and have begun shedding spent petals from the first of their flowers to open.

Observers noted that sprayers could be seen throughout the region applying preventative fungicides in advance of the approaching storm system.
