This report covers conditions and observations made on Monday, February 16, 2015.

Today’s pictures show three down-the-row views of plantings at different stages in the bloom cycle. First a Nonpareil and Aldrich planting shedding its petals in the Chico area of Butte County, followed by a Nonpareil and Butte planting showing the Nonpareils significantly ahead of the Butte. Finally, a shot of a Nonpareil and Wood Colony planting near Woodland, showing a nice overlap between varieties.

Clear skies and a light breeze made for a wonderful Presidents Day in the Sacramento Valley as bloom continues to get a boost from Mother Nature. Early morning temperatures in the low 40’s rapidly gave way to afternoon highs in the mid 70’s. Light winds did nothing to prevent bees from foraging during the day. With ideal weather as the bloom reaches its peak in the northern region, observers noted that bees were out in full force, putting in a solid seven hours of work.

Bloom is nearly at its overall peak in the northern region. The early blooming Sonora is rapidly shedding its petals leaving the developing nutlet in its jacket. Nonpareil and its associated pollenizers should be at peak bloom today or tomorrow. More petals are shedding each day from the California type varieties. In the Chico area, the Carmel is nearly at peak bloom with significant petal fall being observed, while in the Williams area, the Carmel has only about one quarter of its flowers open and available for pollination. There is a similar variation in the Butte and Padre plantings as well, with plantings in the Chico area presenting approximately 50% of their flowers for pollination, while the Williams area has only 10% of their flower open and available to the bees. This significant variation is likely due to the heavier soil types present in the Williams area.

Conditions in recent days have been very supportive of the bloom and growers in the region have been very pleased with their prospects thus far.
