Pollen must travel from the anther (male organ) of one flower to the stigma (female organ) of a receptive flower, where the pollen germinates, fertilizes the egg, and creates a seed or seeds. Many fruit and nut trees rely on honey bees, mason bees, or bumble bees to move pollen.
As with other cucurbits, melon flowers require pollination to set fruit, so be kind to the bees! here’s how to pollinate flowers yourself to increase yields (squash flowers are shown as an example, but the principle is the same for melons). If your muskmelons taste bland, the trouble could be a lack of magnesium in sandy soil.

To discourage self-pollination and promote cross-pollination, the pollinia typically are separated from the stigma (female part of the flower that receives the pollen) by a flap of tissue called the rostellum. The rostellum also aids in the transfer of the pollinia from the pollinator to the stigma.

Inadequate pollination results in poorly developed, misshaped, unsalable fruit. Weather extremes can cause flowers to drop and poor fruit set can in spite of good pollination. In most cases, pollination involves the transfer of pollen from male structures (anthers) of the flower to the female structures (pistils) of flowers.
