Poor or incomplete pollination
Plants with poor pollination may have reduced fruit set.
Pollination occurs when grains of pollen are transferred from the anthers of one cultivar's flower to
the stigma of another cultivar's flower. This is done by insects. In almonds, normal pollination does
not occur when temperatures fall below 55 F, in rainy weather, or when winds are strong. Plant varieties
with good bloom overlap.
