Can anyone help me here. I have a sweetcorn bed in which I planted 6 normal size corn and about a dozen of the mini corn. The have all come up lovely, the big sweetcorn has the flowers at the top and lots of cobs on each plant and is about 4-5 foot high but the mini corn is about 6ft tall (mini huh) with no flowers or cobs. What is going on here. Lots of leaves on the mini ones which are lovely and healthy looking. Heeeeelp
