Q. My sweet corn is growing vigorously, but the wind and rain topple almost all of them, they are almost 12" high now. Since I planted them in the box using seeds, the roots may not be so deep as tomatoes, which are transplanted deeper. The corn topples at the root zone. Now I am using tomato trellis string to hold them up. Its not a good plant for the grow box I guess, or am i missing some planting tips here?
A. Corn roots by nature grow close to the surface. Because of the light soil medium in Grow-Boxes it is easier for the weather to knock corn down. However, It will usually stand up again by itself, unless the bad weather continues for some time. After the corn tassels it sometimes will not stand up after being knocked down. Tying string to support it is usually not necessary. Corn sends out adventitious (supplemental lateral), or prop roots, which help support it, and give it the strength to right itself.
