This report covers conditions and observations made on Tuesday, February 23, 2016.

Photos for today’s report in the southern region illustrate the various stages of bloom in different varieties. The first photo shows the petal fall and jacket stages in the Sonora variety in the Chowchilla area of Madera County. The second photo provides a down-the-row shot of a Nonpareil and Monterey orchard in the Selma area of Fresno County. Taken in the Arvin area of Kern County, the third photo provides a shot of the jacket stage in the Monterey variety.

Sunshine and clear skies filled the South San Joaquin Valley on Tuesday. Overnight temperatures in the low 40s yielded to daytime highs in the low 70s. Mostly clear skies and calm winds allowed bees to put in 7 hours of very concentrated work.

Bloom is winding down in the southern region. Almost half of the flowers on the early blooming Sonora have shed all of their petals while only one-fifth of the flowers are presenting for pollination. Nonpareil, Monterey, Carmel, and California-type pollenizers are a little over a day behind Sonora and shedding petals quickly. The late blooming Butte and Padre are holding on to their petals better than the early bloomers. They still have around half or more of their flowers presenting for pollination. Varieties within individual orchards continue to have excellent overlap giving bee plenty of opportunities for cross pollination where flowers are still viable.

Growers with access to water are irrigating and applying nutrients through their irrigation system as trees begin to pull moisture and nutrients from the soil. Floor management continues as growers try to regulate orchard temperature in case of cold weather by keeping vegetation close to the ground.
