  1. Wind Pollination Challenge: Corn’s reliance on wind for pollination can be challenging indoors, where air circulation is often limited compared to outdoor conditions. This limitation can hinder the natural dispersal of pollen from the male flowers (tassels) to the female flowers (silks) on the lower part of the plant.
  2. Manual Pollination Technique: To ensure proper pollination and successful fertilization, you can adopt a manual pollination technique. When the corn plants begin producing tassels (male flowers) at the top, you can gently shake the plants to encourage the dispersal of pollen. This mimics the action of the wind and facilitates the transfer of pollen to the silks (female flowers) lower down the plant.
  3. Timing Is Key: Timing is crucial when implementing manual pollination. Wait until the tassels are fully developed and shedding pollen, which typically occurs a few days after they first emerge. You can check for pollen by gently tapping a tassel over a piece of paper; if pollen falls, it’s ready for pollination.
  4. Silk Care: When applying pollen to the silks, it’s essential to handle them delicately. The silks are the receptive parts of the female flowers, and they extend from the developing ears of corn. Carefully lift the silk covering from an ear and expose the kernels beneath. Apply the pollen by gently brushing the tassel over the silks, allowing the pollen to fall onto the exposed kernels.
  5. Repeat as Necessary: Since indoor conditions may not provide as effective pollen distribution as outdoor wind, consider repeating the manual pollination process several times as new ears of corn develop. This ensures that each ear receives ample pollen for successful fertilization.

By embracing the role of a surrogate wind and meticulously facilitating the pollination process, you can overcome the challenge of wind pollination in an indoor setting. This hands-on approach guarantees that each ear of corn is adequately pollinated, ultimately leading to the development of plump and juicy kernels ready for harvest.
