This report covers conditions and observations made on Monday, February 23, 2015.

The photos for today’s report display nutlet development of the Nonpareil variety in the Madera area, followed by down-the-row views of the Nonpareil and Fritz, showing the completion of its bloom and the declining bloom of the Butte and Padre, near Chowchilla.

Rain made its way through the southern region on Monday, providing some areas with a good soaking while other areas received very little precipitation. Well over an inch of rain fell from the early morning through noon in areas east of Highway 99, while areas to the west received from trace amounts to a few tenths of an inch. The rain kept bees in their hives for much of the morning, although observers noted good activity between and after rain events. Depending on local weather, from 3 to 5 hours of good bee activity was noted in the orchards, which was a welcome sight after a weekend of little bee activity.

The amount of flowers available for pollination in many of the southern San Joaquin Valley’s Nonpareil and California type plantings is dwindling rapidly. Weather events over the weekend have left behind mostly leaves and stray petals, with only a small proportion of the flowers remaining available for pollination in these cultivars. Mission, Butte, and Padre are all benefiting from afternoon sunshine as there are still significant levels of flowers available for pollination in these late blooming varieties. Cooler temperatures that accompanied the storms have slowed the rate of growth and the progression of nutlets emerging from their protective jackets

The stormy, wet conditions of the past few days have delayed some routine orchard tasks. All in the region are watching the weather forecast for signs of cold weather and the threat of frost as the nuts grow and emerge from their jackets.
