Corn in sfg-how deep do roots need to grow?
My sfg is only 4x4. I plan this season, only using it for corn. When plotting out my garden (we increased it and changed some things around), I decided to put a mesh screen under the raised bed. Should this be removed before I plant the corn? The bed sits on dirt that is very hard and has rocks in it, but if the roots need that space to grow, they'd at least have a fighting chance. Or, can the screen stay and the corn do just fine?
