This report covers conditions and observations made on Tuesday, February 17, 2015.

The first of today’s photos for the central region are a down-the-row shot of a Nonpareil and Aldrich planting with varying amounts of petal fall near Manteca in San Joaquin County, followed by the popcorn and bloom stage in the Padre, and a down-the-row shot illustrating the overlap between the Nonpareil and Fritz in the Waterford area of Stanislaus County.

The central region experienced the heaviest fog it’s seen since the beginning of bloom, covering much of the Northern San Joaquin Valley until late morning. Temperatures struggled to make it in to the mid-60’s after early morning temperatures were reported in the low 40’s. Fog lifted to reveal scattered clouds and higher wind speeds than the past few days. As a result, bees stayed in their hives longer and remained inactive for most of the morning. Observers reported 5-6 hours of good activity mostly in the afternoon.

Bloom continues to advance quickly in the central region. The early blooming Sonora is now well into the petal fall stage, while the Nonpareil and most of its pollenizers have reached their peak in the majority of the region. Advanced examples of the Nonpareil and California types are now also beginning to shed petals to the orchard floor. The Carmel has made great strides in the past two days and is racing to catch up with its associated Nonpareil. Butte and Padre have also picked up the pace, with a significant proportion of the flowers of these late blooming types now attracting the attention of the bees.

Overall, growers have been happy with the bloom progression and the degree of overlap between varieties. Other than the early morning fog, this week’s excellent weather has provided ample opportunities for the bees to cover the rapidly advancing bloom.
