This report covers conditions and observations made on Thursday, February 12, 2015.

These three photos show a close up of a bee foraging for pollen in an open Sonora flower, a down row view of a Nonpareil and Fritz orchard with a higher percentage of Fritz flowers open than Nonpareil, and a close up of a late blooming Butte bud in the green tip stage of development.

Warmer temperatures and clearer skies finally reached the South San Joaquin Valley. After patches of morning fog burned off early temperatures in the low 40’s rose quickly to afternoon highs in the low to mid 70’s. Fog gave way to calm wind speeds under clear skies leading to the best day of bee activity so far this season. As more flowers begin to open, bees kept up the pace putting in 7 hours worth of work. Warmer weather provided a much needed jolt to the southern region that got buds moving and more flowers presenting for pollination.

As skies cleared and temperatures rose, buds began to advance at more normal pace. The early blooming Sonora variety has nearly a third of its flowers presenting for pollination. The Nonpareil cultivar is approximately 3 to 4 days behind. Overlap with the California type varieties and Monterey appears ideal at this point with flowers presenting for pollination in lock step at the same rate. The Carmel variety, as with the other regions, continues to lag 2 to 4 days behind the Nonpareil. The late blooming Butte and Padre cultivars remain relatively stagnant with no measureable flowers presenting for pollination and higher percentage of dormant buds than any other region.

A major observation made this year in the southern region has been a big variation in bud development between blocks making the overall development harder to gage. This is not entirely surprising given the extreme drought conditions faced in the region. Every orchard site has a different water situation and different levels of stress, leading to varied tree health and bloom timing.
