This report covers conditions and observations made on Monday, February 22, 2016.

Photos in today’s report for the north show the jacket stage of the Sonora variety in the Woodland area of Yolo County, the jacket stage of the Monterey variety in the Arbuckle area of Colusa County and a down-the-row shot of a Price and Aldrich orchard in the Durham area of Butte County.

Morning lows dipped into the low 40s, but clear skies and sunshine warmed the air quickly as temperatures rose into the low 70s throughout the Sacramento Valley. Winds from the north reached 8 to 10 miles per hour in the morning, with gusts of 14 to 16 miles per hour reported along the west side of the valley. With the warm morning temperatures, bees were able to get out and work by mid-morning. Observers reported 6 to 7 hours of good activity in areas where winds were lighter.

With bloom in the northern region winding down and moving well into the jacket stage, the later blooming Butte and Padre varieties still have measurable amounts of bloom available for pollination. Windy, warm conditions have accelerated the rate of petal fall. The Sonora variety has completely exited the bloom stage, with Nonpareil and its California-type pollenizers quickly losing their remaining petals. In these earlier varieties, nutlets are beginning to be seen poking through their jackets although no jacket split is being observed.

Growers are continuing to apply nitrogen where necessary to help support their quickly developing crop. Those with access to water are irrigating to soak fertilizers into the root zone, and making sure that their irrigation systems are working properly in the event they’re needed for frost protection.
