Late spring frosts, diseases, or drought will trigger the cycle by severely reducing nut yield in a particular year, increasing flower production the following year. Walnut trees will bear fruit once a year. However, the amount will vary each year. Occasionally, walnuts don't produce fruit during the growing season due to stressors such as drought, pests, or lack of nutrients.
Walnut trees produce walnuts around 7 years of age. In California, shipping delays affect not only imports but also exports. Without a way to ship Christmas crops such as almonds, walnuts and pistachios, farmers are losing out on markets and profits abroad. New walnut trees don't usually produce fruit for about 6 years, they may settle again after being pruned.
As Dovefromabove says, a little food can stimulate this process. It could be that when the tree bloomed, pollinators were suppressed in some way, such as a cold snap or heavy rain.
