This report covers conditions and observations made on Wednesday, February 25, 2015.

Taken in the northern part of Stanislaus County, the photos in today’s report show the developing nutlets of the Sonora and Fritz varieties, followed by the delayed bloom of a particularly vigorous Carmel planting. While the Carmel in this shot appears to be in full bloom, notice the large amount of petals on the ground, giving hint to the fact that the bloom in this planting is also in decline

Beautiful spring-like weather provided the northern San Joaquin Valley with additional pollination hours, as bloom is nearing completion. Morning lows in the upper 30s quickly gave way to highs in the mid 60s with very little wind. Given these favorable conditions, observers noted 7 hours of very good bee activity. As has been the case for the past few days, Butte, Padre and Mission plantings have drawn the bee’s greatest attention as they provide the largest amount of bloom remaining in the region.

Bloom is nearing the end in the central region. The early blooming Sonora variety has no viable flowers available for pollination, while nutlets are starting to emerge from their jackets in measurable levels. The bloom of the Nonpareil variety, along with its pollenizers, has declined significantly in recent days and has now fallen to 10% or less across the region. While the number of viable flowers of Butte and Padre is also receding, these late blooming types still have approximately half of their flowers available for pollination and are drawing most of the bee’s attention.

In addition to providing support for the developing nutlets, recent weather conditions have also given growers an opportunity to get into their orchards. Orchard maintenance continues, with growers mowing vegetation and applying fertilizers as needed.
