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. All walnut trees produce walnuts, but the amount of nuts produced will depend on the climate and the nutrients available. Their trunks are in such demand for veneer that “walnut rustlers have taken away the trees in the dark of night and have even used helicopters in their operations.
So how often can you expect your backyard nut to produce these delicious and healthy fruits, nuts, whatever you want to call them?

Nuts need a little feeding; on the farm, ours used to be covered with farm manure; yours could probably use a spring dressing of a balanced fertilizer (one with nitrogen and potash). Tree nuts, led by almonds, walnuts and pistachios, were estimated at 4.5 billion pounds without shell, up 24% from the previous season. Black walnuts are still cultivated and used for nut production, but the shells are harder to crack and the flavor is much stronger than that of an English nut.
He said that approximately every 5 years he doesn't get a crop due to the loss of rain and the elements, so this may also be true for walnuts. The walnut trees near where I live didn't produce nuts this year last year there was a brilliant harvest, maybe the weather had a lot to do with it and they will produce next year let's cross our fingers. Whether you enjoy harvesting fallen walnuts or can't stand them dirtying your garden, at some point your walnut tree will age and slow down. When surrounded by other trees in the forest, black walnuts grow straight and tall with few, if any, lower branches.
This prevents flowers from blooming, which means there is no pollination, which means there are no dirty nuts to clean in the fall. Not to mention, walnut fruits will litter your lawn as they fall, creating a mess of green, blackened fruits and peels. In orchards, walnut trees only last about 35 years, according to the University of California, Davis.
