Cross pollination is the transfer of one flower to the stigma of another with a different genetic composition, as by the action of wind or insects or deliberately by a botanist. Tomatoes have “perfect” blossoms, meaning that they contain both male and female organs and are self pollinating. The transfer of pollen to egg is initiated by motion of the plant, normally supplied by wind current. If motion does not occur the blossoms do not pollinate, but fall. If you fear not having fruit due to blossom drop, gently shake the plants twice a day to simulate wind-like motion. Within a week you should see many new tomatoes set if other conditions are adequate. How long does it to take sweet corn to develop from the first appearance of silk to harvest? About five days are required for complete pollination after the first silk appears. Harvesting begins approximately 20 days after first silking. To save my corn crop from worms, I have been told to put a drop of mineral oil inside the tip of each
