Cohen is working on a three-year study of the types of pollinators of the Hass variety, which doesn’t attract honeybees and bumblebees the way other tree crops do.

'Unrelenting' fog aids Central Valley fruits and nuts
'Unrelenting' fog aids Central Valley fruits and nuts

Tule fog blankets a walnut orchard last month in Yolo County. The low-lying fog layer, named after a sedge native to Central Valley marshes, is created by moist soils capped by a high-pressure weather system. Farmers and researchers say persistent fog throughout the valley in recent months could help the region’s fruit and nut trees achieve the winter dormancy they need to bloom successfully.

A lemon tree in a Tulare County residence, left, shows classic symptoms of citrus yellow vein clearing virus, which include vein clearing when viewed from the top of the leaves and water soaking when viewed from the bottom, center and lower right. At top right, a sour orange rootstock (lighter green plant) exhibits vein clearing while the adjacent Meyer lemon scion is asymptomatic.

During harvest at a San Joaquin County orchard, a mechanical sweeper moves scattered walnuts that have been shaken from the trees into windrows, after which the nuts will be picked up by a harvester. The 2025 crop is estimated at 710,000 tons, up 18% from 2024’s production of 603,000 tons.

This reservoir at Brokaw Ranch Co. in Santa Paula holds 1 million gallons of water and is one of two reservoirs on the farm. Because it is gravity fed, it can deliver water even when there’s no electricity. This allows the farm flexibility in how and when to use irrigation.

Organic seal helps boost 'phenomenal' date market

Workers stand on a picking tower platform as they harvest organic Medjool dates for farmer David Kohl at a Coachella Valley orchard in 2022. The vast majority of dates grown in Riverside County, which dominates U.S. production of the crop, are certified organic. Growers and marketers say organic certification has boosted sales of California dates, which have seen growing demand in recent years.

Tools to control aggressive red leaf blotch a priority
Tools to control aggressive red leaf blotch a priority

These photos show different stages of red leaf blotch, which was found throughout the state this year, particularly in almond orchards where growers may not have applied petal fall sprays or had reduced the number of sprays. As the fungal disease progresses, the blotches may become necrotic and eventually cause leaf drop. In severe infections, the disease may reduce yields.
