I start my mini-corn off in individual pots in the greenhouse at the end of april,when danger of frost has passed,plant them out, I use mine as a wind-break
around the plot. You pick the cobs before they are pollinated so it does n't matter
how you plant or space them. You usually get 3 or 4 cobs per plant and if you get
a glut freeze them dont leave them on the plants ,they get big and tasteless.
Hope this helps/ angle shades x
