This report covers conditions and observations made on Wednesday, February 10, 2016.

Taken in Maxwell, the first two photos from the northern region illustrate the advanced stage of Sonora bloom in an early blooming orchard along the west side of the valley, and a bee approaching a flower to forage for pollen. The third photo shows the developing bloom in the Aldrich variety in Durham.

Calm winds and sunshine continued their presence in the Sacramento Valley on Wednesday. Overnight lows in the low-40’s gave way to daytime highs in the mid-70’s. Very few clouds and light winds made very good flying conditions for bees to work the rapidly progressing bloom.

Bloom is rapidly progressing in the Northern region. The early blooming Sonora variety is approaching 10% bloom, with orchards along the west side of the valley being the most advanced. Nonpareil and its California type pollinizers are roughly 2 days behind, with Nonpareil developing slightly slower than others. Observers reported that Carmel and Monterey are roughly a day behind Nonpareil.

Growers are looking at weather forecasts for the upcoming week as they plan the first round of fungicide sprays. Temperatures are expected to remain in the mid-to-upper-70’s through the weekend, and early next week with overnight lows staying in the upper-40’s. These temperatures will help bloom progress rapidly, before the potential of a rain event in the middle of next week.
