Pests in Gardens and Landscapes

Poor or incomplete pollination

Plants with poor pollination may have reduced fruit set.

Solutions

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.
