I am growing corn for the 1st time & I seem to be winning, except, I have noticed the soil around the bottom of the stems is falling away as they are growing bigger, and the roots are showing a little. Is this normal? I keep covering them up but worry I may damage the corn. It is strong and healthy and they were dug in deep 45cm when planted. I just want to know if this is normal & are they air roots?

I hill the soil up around the plant when they are about 30-40cm high. This gives them soil for the roots to grow in. I also run a little fertiliser beside the plant before hilling up.

Sweetcorn does look as though the roots are showing as it grows taller. They help to support the plant and are quite normal.
