The following is the latest California Fruit and Nut Review report from the National Agricultural Statistics Service’s Sacramento, Calif., Field Office:

December crop comments

Grape and pomegranate harvests were complete. Grape growers were pruning, irrigating, cultivating, and removing old vines.

The extent of frost damage due to cold mid-December temperatures was still being determined, but damage appeared to be localized to small areas.

Almond hulling and stockpiling was completed in early-December. Nut trees began entering dormancy by the end of the month. California’s strawberry season started slowly this year due to the wet and cool weather.

The harvest of Navel oranges, Satsuma and Clementine mandarins, grapefruit, and lemons continued.

In citrus orchards along the coast and in the Central Valley, helicopters and wind machines were deployed to increase air circulation to combat freezing temperatures in mid-December. Growers also used orchard heaters and ran irrigation water to limit the drop in temperature. The extent of damage was still being assessed.

Normal spraying and maintenance continued in citrus orchards.

Florida citrus

Temperatures in the 70’s and 80’s and lows in the 30’s and 40’s were reported during December. Increased rainfall helped relieve drought conditions. Overall, the weather was beneficial to citrus progress. Harvesting of Murcott tangerines has begun. Weekly Navel orange harvesting picked up in early December, but dropped off at the end of the month.

Most of the processing plants have opened and are mainly receiving early and mid-season oranges and grapefruit. Grove activity included limited herbicide applications and mowing. Grove caretakers surveyed groves for citrus greening, removed affected trees, and sprayed trees for Asian citrus psyllid control.
