At Fresno State’s farm, the pistachios looked normal hanging on the trees. Many were empty inside. It is the kind of shortage that can hide in plain sight until harvest.
A report from China’s Economic Observer says Sam’s Club has restricted customer purchases as pistachios have become scarce. The report offers no quantity or duration for the limits, but its retail detail points back to a crop problem: fewer nuts reaching the market.
A full-looking tree, a light crop
At the Fresno State farm, manager Rob Willmott described a season in which the nuts looked ordinary on the tree, while many proved empty. The farm’s losses reflected a wider San Joaquin Valley problem after extreme March heat affected pollination, according to ABC30’s report.
The heat arrived during flowering, when timing matters. Ag Alert reported that heat and the trees’ alternate-bearing pattern combined to put the 2026 harvest at less than half of the previous year’s record crop, according to its October harvest report.
Higher prices, fewer nuts to sell
A short crop can lift grower prices without restoring the revenue lost to lower volume. Jeff Nichols, vice president of supply chain and grower relations at Nichols Farms in Hanford, told Ag Alert that higher prices may not make up for the reduced harvest. The arithmetic is familiar to anyone who has watched a strong price meet a disappointing bin count.
The store limits are a visible symptom, not a measure of how long the tightness will last or how widely it applies. The Economic Observer report supplies no detail on the scale of the restrictions, so it cannot establish what buyers or handlers will face as the season’s crop moves through the market.
For California pistachios, the useful distinction is between nuts on a tree and nuts that make it into saleable product. That gap is where a heat-stressed bloom turns into a market story.
