I am pleased to share that California has enjoyed a strong season so far, with prices remaining notably high for much of the year. While we experienced some price moderation in late July following the summer peak, this season—like last year—has been both prosperous and overwhelmingly positive. The steady demand and robust pricing continue to reflect the exceptional quality and premium reputation that California avocados command in the market.
The California crop estimate was revised from 375M to 340M lbs. in May, and the current trajectory looks to be on track to meet that mark. By late July, we’re nearly 80% through the season, with over 260M lbs. harvested. The South region saw exceptional gains, with harvest up 60% compared to last year.
We wrapped up the GEM season in early July, and it was a clear success. Fruit movement was steady, demand consistent, and Index Fresh closed with a record-high 51% GEM market share. Grower returns per bin were strong, overall quality looked good, and the California Crema GEM brand launch received enthusiastic retail response across the country.
Weather has been largely stable, with no major spikes impacting the crop. I’d like to thank our agronomist, Gerardo Aldunate, for working closely with many of you to improve yields and implement new techniques. Gerardo and our Field Reps led an engaging series of Gather & Grow In-Field events in June and July, with more regional events planned this fall, including pruning and girdling demos.
Looking ahead, I’m excited about new acreage coming for 2026 and the strong prospects for next year’s Hass and GEM crops. Your partnership and commitment to California avocado excellence continue to inspire us. Thank you for your trust and the privilege of working alongside you.
As the summer season arrives across California’s avocado groves, it’s the perfect time to revisit best practices for tree health and fruit quality. In June and July, our team at Index Fresh hosted regional Gather & Grow in-field meetings to discuss pressing seasonal topics with growers. For those who couldn’t attend, we’re sharing the highlights and actionable tips below so your orchard can thrive through the critical months of July to September.
Understanding Phenology: Setting the Stage
Avocado trees are finishing the demanding flowering and fruit set phases. These have required significant tree energy. Now, exponential fruit growth begins, coinciding with key periods for shoot and root development. Your summer decisions will have a lasting impact on fruit size, yield, and tree vigor throughout the season.
Summer Cultural Practices for Success
Fertilizer Plan
The next 12 weeks mark rapid fruit growth—a stage of high demand for nutrients, especially nitrogen, potassium, and zinc.
Adjust your fertilizer applications to match both crop load and shoot growth. A targeted plan now supports both developing fruit and new canopy.
Irrigation Management
Well-timed, adequate irrigation is essential during early fruit development. Good water management reduces fruit drop and maximizes fruit set.
As temperatures rise, shorten intervals between irrigations to minimize stress and optimize fruit size. Monitor your soil moisture and tree needs closely.
Pruning Practices
Goals: Improve light penetration, make harvesting safer and easier, streamline spray coverage, and ultimately maximize yield and fruit quality.
How-To:
Cut back the tallest branches to lower tree height.
Remove branches growing into adjacent trees or work alleys.
Eliminate poorly placed, crossing, or weak shoots.
Remove dead wood for canopy health.
Maintain a healthy balance between fruit- and leaf-producing shoots.
Protect newly exposed branches from sunburn with a water-thinned white paint.
Disinfect pruning tools between each tree to prevent disease transmission.
Mulching for Roots and Soil Health
Mulch renewal is timely now. A fresh layer:
Promotes fine root growth.
Suppresses Phytophthora root rot.
Improves vigor by keeping soils cooler and more moist, with better nutrient and water retention.
Heat Management Strategies
With peak summer heat possible, water is your first line of defense.
Apply up to 50% more than your typical irrigation volume the day before an anticipated heatwave.
Use shorter, more frequent irrigations during heat events to reduce crop stress and prevent fruit drop.
We encourage you to review these practices with your Field Representative and adapt them to your unique conditions. As always, Index Fresh remains available for consultation or in-grove advice—reach out if you would like personalized recommendations.
Overhead sprinkler systems are proving to be a powerful tool for protecting avocado orchards from extreme heat. Research has shown that using these systems can drop the air temperature around avocado trees by 7–12°F, providing a critical buffer against heat waves that can cause stressed trees to shut down and crops to suffer severe damage (Miller et al., 1963; Lomas and Mandel, 1973). More recently, a 2022 study published in Nature documented how Israeli researchers saw up to a 100% increase in avocado yields when using canopy-cooling systems during heat spikes. In trials across three Israeli orchards—where temperatures soared to 113°F—overhead irrigation reduced air temperature by 18–21°F and boosted relative humidity by 16–18%. While the concept isn’t new or particularly high tech, the adoption of overhead sprinklers in avocado farming is on the rise as growers seek practical strategies to mitigate the growing challenge of extreme heat.
Evapotranspiration is the key process at work. As plants transpire, they release water vapor through their leaves, cooling the surrounding air—a natural effect similar to condensation on a cold glass. Overhead sprinklers amplify this cooling by adding moisture directly to the orchard environment, resulting in even greater temperature reductions and increased relative humidity.
At Brokaw Ranch Company in Santa Paula, nearly 50 acres are equipped with overhead sprinklers—an investment in preparation for the inevitable 100-degree days of August and September. Ranch Manager Nathan Lurie reports that the system is effective, and the ranch now considers overhead sprinklers standard practice with all new plantings.
Hot temps trigger avocado trees to close their pores
When temperatures rise above 88°F, avocado trees will start to enter the danger zone. Their stomates—leaf pores crucial for gas exchange—close to conserve water under intense heat and low humidity. This defense mechanism, however, restricts both water uptake and respiration, stunting photosynthesis. If these high temperatures persist, trees can experience fruit drop, reduced yields and size, and, in extreme cases, fatal stress. Because avocados are tropical trees with shallow root systems, they are especially sensitive to heat events, which are becoming increasingly common in California’s avocado regions.
According to Lurie, advances in weather forecasting allow growers to anticipate and prepare for heat waves with precision. One of the best preventive measures is to increase ground irrigation in the days ahead of a forecasted heat spike. During a heat event, orchards equipped with overhead sprinklers, like Brokaw’s, activate the system hours before temperatures reach their peak. Water supply and pressure limitations mean not all orchard sections can be irrigated simultaneously, so the sprinklers are cycled in advance to rotate through each section.
The overhead sprinkler system, 16 sprinklers per acre, disperses large droplets for about 15 to 20 minutes in each area—just enough to ensure the canopy is evenly moistened. Lurie explains that this system strikes an optimal balance: it maximizes canopy coverage while still conserving water.
The overhead sprinklers complement increased ground irrigation. By cooling the canopy, the sprinklers help keep the stomates open, allowing trees to continue metabolizing and making use of the extra irrigation, instead of shutting down under heat stress.
Overhead sprinklers are especially vital for newly planted trees in heat-prone areas, giving them a greater chance to survive their critical establishment years. For mature trees, the system helps prevent crop losses and canopy/limb damage from severe sun burn.
“Overhead sprinklers help prevent loss from heat damage to the current crop and often next year’s crop. In extreme heat, you could be looking at limb damage and reduction of crop even two to three years out,” notes Lurie.
While growers in other crops have used overhead sprinklers for decades to mitigate heat and frost, avocado growers are only now widely adopting this technology. Much of the foundational research comes from Israel, where heat challenges mirror those California now faces—especially in the southern regions and inland Ventura County.
For growers considering this enhancement, Index Fresh Field Representatives can assist in evaluating and implementing overhead sprinkler systems, offering guidance where the return on investment may be substantial—particularly if the alternative could mean significant crop or tree loss.

As we transition from winter to spring, crucial phenological processes begin in avocado orchards, particularly the Flowering and Fruit Set. These stages are critical precursors to the next harvest. To optimize tree health and productivity during this period, implement the following cultural practices:
Fertilization
Initiate fertilizer application to support flower development and fruit set
Adjust fertilizer quantities based on flowering intensity
Consider foliar applications of micronutrients to boost tree health
Irrigation Management
Maintain adequate soil moisture during flowering, fruit set, and early fruit development
Monitor soil moisture levels regularly and adjust irrigation schedules accordingly
Implement deficit irrigation strategies if water resources are limited, but avoid water stress
Pollination
Monitor flowering progression closely
Introduce honeybee hives when approximately 10% of flowers have opened
Consider supplemental pollination techniques in areas with insufficient natural pollinators
Crop Load Management
Assess fruit set and consider early thinning of excess fruit
Remove small or damaged fruit to improve overall crop quality
Balance crop load with tree vigor to prevent alternate bearing
Pest And Disease Control
Implement Avocado Thrips and Persea Mite control measures based on monitoring results
Be vigilant for symptoms of root rot, which is most stressful to trees in spring
Apply appropriate treatments if root rot is detected
Monitor for other seasonal pests and diseases, such as fruit spotting bug or anthracnose
Weed Management
Control weeds to reduce competition for water and nutrients
Use mulch or cover crops to suppress weed growth and improve soil health
Time weed control to avoid competition with avocado flowers for pollinating insects
Orchard Floor Management
Maintain a clean orchard floor to facilitate harvest operations
Consider cover crops to improve soil structure and beneficial insect populations
Manage ground cover to balance ecosystem services with practical orchard management
By implementing these practices, growers can optimize tree health and productivity during the critical spring transition period, setting the stage for a successful avocado harvest.
The 2025 California avocado season began with great momentum in mid-January, marking an earlier start than usual. Thanks to a short supply of 48s from Mexico during January, we were able to work together to bring California fruit to market just in time to meet the heightened demand during the Super Bowl period.
Early harvesting primarily consisted of size picks, but the favorable market conditions also allowed growers the opportunity to conduct maintenance and anti-theft picks at competitive price levels.
Looking ahead, California is poised for a strong crop this year, with volumes expected to be similar to the 2024 season. Last year’s final numbers reached 386 MM pounds across all varieties. For 2025, initial estimates project 355 MM pounds of Hass avocados, 11 MM pounds of Lamb Hass, 8 MM pounds of GEM, and 1 million pounds of other varieties such as Reeds and green skins.
The U.S. avocado market is currently facing notable challenges. Mexican supply has fallen short of meeting regular weekly demand, and recent tariff uncertainties have further tightened availability. These factors have created robust demand for California fruit at premium prices over the past several weeks.
With ongoing uncertainty surrounding Mexican supply, retail buyers are increasingly turning to alternative sources to meet their needs. California avocados stand out for their quality, consistency, and reliability—making them a top choice for buyers nationwide.
GEM avocados are also generating excitement among retailers. Our newly launched California Crema GEM campaign has already sparked enthusiasm from both new buyers and long-standing GEM customers eager to expand their programs. Please coordinate closely with your field representative to ensure a smooth harvest process.

Native to the southeastern United States, the avocado lace bug is a notable pest that causes damage to avocado trees. Its presence has been documented as far south as San Diego County and as far north as Ventura County. Here are some essential facts about this pest.
APPEARANCE: Eggs are laid in an irregular pattern, sometimes in loose rows, stuck to the lower leaf surface and are covered with irregular globules of a black, sticky, tar-like substance excreted by adults that may protect eggs from natural enemies. Eggs will appear like grains of black pepper. Adult avocado lace bugs are small, have clear, lacy wings (about 2mm long) with a single dark band on their bodies, yellow legs, and antennae. They are visible to the naked eye.
LIFE CYCLE: Lace bugs are immobile most of the time. They feed on the underside of leaves, causing chlorotic blotches that can become necrotic. Severely damaged leaves may drop prematurely.
DAMAGE: Heavy lace bug feeding can lead to defoliation, sunburned fruit and wood, and stressed trees, potentially reducing yield.
LOCATION: Lace bugs have been spotted in groves spanning from San Diego to Carpinteria. The lace bugs live in colonies on the lower surfaces of leaves, often with adults, eggs and nymphs together.
OTHER HOSTS: Besides avocado trees, the lace bug also feeds on the camphor tree (Cinnamomum camphora).
TIMING: Lace bug populations tend to build in July, peak around September, and decline to low densities from January through May. Because they are largely immobile, they tend to disappear as older leaves drop off and the new leaves emerge during the spring flush
MANAGEMENT: Management strategies may include restrictions on the movement of host plant materials, insecticide screening trials, and evaluation of natural enemy releases.
NATURAL ENEMIES: Green lacewing larvae were historically identified as natural enemies of avocado lace bug. However, recently Erico Ferro, PCA, notes he has not observed natural enemies feeding on any of the different stages of lace bug (egg, nymphs or adults) including lacewing larvae. Predators may feed on them but should not be relied on to control a population.
PESTICIDES: There are several pesticides that can kill lace bugs and are tolerated by green lacewing larvae.
CONTROL: UC recommends various products to help control lace bugs. To learn more about how to control the pest, email info@indexfresh. com for UC’s management guidance and evidence-based recommendations from PCA Enrico Ferro.
