This report covers conditions and observations made on Wednesday, February 17, 2016.

Taken in the Ripon area of San Joaquin County, the accompanying photos of the central region show the progression of bloom in a Butte and Padre orchard, the bloom and petal fall stage in Nonpareil, and a grower applying fertilizer prior to oncoming rain.

Overcast skies covered the Northern San Joaquin Valley on Wednesday. Overnight lows in the mid 40s gave way to daytime highs in the low 70s though the sun rarely broke through clouds. Bees decided to remain in the hive most of the day as gusty conditions combined with overcast skies prevailed in the afternoon. Only two to three hours of poor bee activity were observed.

Most varieties in the central region will be peaking Thursday or Friday. The early blooming Sonora achieved maximum numbers of flowers presenting for pollination today with over 70% open flowers. Sonora is now beginning to lose it petals quickly. Nonpareil, Monterey, and California-type pollinizers are a day or two behind Sonora and preparing to peak with over 75% of flowers presenting for pollination, with some measurable petal fall being observed. Carmel is about a day behind Nonpareil. The late blooming Butte is coming on fast with over 50% of its flowers presenting for pollination with the Padre cultivar half a day behind.

Orchards were relatively quiet with fungicide treatments completed in most orchards. A few growers were trying to finish their applications before the wind shut them down in the morning.
