This report covers conditions and observations made on Tuesday, February 16, 2016.

Taken in Madera County, the first two photos accompanying today’s report show the pink tip stage of the Fritz variety and the advanced stage of bloom in the Nonpareil variety. The third photo shows a grower continuing orchard maintenance by mowing down grasses in the Arvin area of Kern County.

It was another warm, clear day in the South San Joaquin Valley as bloom continues to progress at a quick pace. Overnight lows with some patchy fog gave way to daytime highs in the mid 70s and plenty of sunshine. Bees were out in full force for a solid 7 hours.

Bloom is taking a big step forward in the southern region. Early blooming Sonora is rapidly approaching peak numbers of flowers presenting for pollination, increasing by more than 20% in 24 hours. Big advances have also been observed in other varieties as well. Nonpareil, Monterey, and California type pollinizers all advanced 30% or more from the previous day. These varieties will likely reach peak numbers of flowers presenting for pollination in the coming days. Carmel continues to progress a day or two behind Nonpareil, and the first measureable number of flowers presenting for pollination was observed in late blooming Butte and Padre. With the majority of the buds exhibiting pink tissue emerging from the sepals it is likely their bloom will progress like the earlier blooming varieties. Variety synchronization remains consistent within individual orchards making for a fairly even bloom.

Most fungicide treatments have been made prior to Wednesday’s anticipated wet weather. Growers with access to water are irrigating ahead of the rain to strengthen the moisture profile in their soil. Orchard floor maintenance continues in order to maintain manageable vegetative growth.
