Triple-digit heat hits lettuce, broccoli, and strawberry harvests in California

Heat waves are traveling through the Western U.S., and the high temperatures are negatively impacting California growers. According to a report by produce distributor PRO*ACT, lettuce, broccoli, and strawberries are among the most affected crops.

The document states triple-digit temperatures are not only impacting produce quality but are also hurting harvesting across the state. Crews have tried adjusting to the scorching weather by starting earlier in the day when the heat is more manageable. However, PRO*ACT says “field conditions remain tough across nearly every commodity.”

The news came after the National Weather Service issued a dangerous heat-level announcement on Thursday. The advisory warned temperatures would put people of all ages at high risk of heat-related illness when outdoors or without access to air conditioning. Authorities have also issued alerts warning about conditions that could lead to explosive fire spread in counties such as Los Angeles and Ventura.

The effect of heat on cruciferous and leafy greens

Most of the state’s South Coast has been subject to the weather advisory since Wednesday, and this is already hurting broccoli and cauliflower. Crops are decreasing in size, according to the report, with an uptick in pin rot and internal defects. Lettuce is also showing signs of heat-caused burn, mildew, and light weight.

The damage to leafy vegetables could pose an issue for growers, as market demand is set to increase with the return of kids to school in September. 

To deal with the burns, lettuce growers are resorting to trimming affected areas as much as possible, according to PRO*ACT.

Strawberries might be a bit bruised

The report also notes that heat waves are affecting strawberries differently depending on what stage of the season they are in. 

Santa Maria and Oxnard strawberries are seeing an increase in size, firmness, and overall quality as they prepare for harvest. Meanwhile, strawberry season in Salinas and Watsonville is winding down, and farmers are reporting more bruising and softness than usual in their final batches.

Oxnard strawberry growers are set to begin harvesting in two to three weeks.
