Home Vegetable Garden Techniques: Hand Pollination of Squash and Corn in Small Gardens

Ed Thralls and Danielle Treadwell

A small vegetable garden can provide homeowners with fresh, healthful food, assist household finances during a time of increasing food costs, and provide a family activity that is both recreational and educational (Figure 1).

The female part of corn is the ears, which are edible. The ears are located lower on the stalks, just above the leaves, at the nodes. One to four ears per stalk is typical, depending on variety. The female flowers are the "silk" (Figure 6). The silk is the same stigma as in squash, but the stigma in corn is elongated. Each strand of silk corresponds to one kernel of corn. Pollination is achieved when pollen grains from the tassels above contact the silks at the nodes.

Two methods of pollen transfer may be used with corn. Cut an entire tassel, and use it as a wand, shaking pollen grains (dust) onto the silks. Alternatively, strip the tassel and deposit the pollen from the anthers directly onto the silks. Either way, the pollen is transferred. Be thorough when dusting the pollen onto the silks, so chances for a bountiful harvest are increased.
