Grow your corn in 2mx2m squares. Plant squash & beans with them, it's an old method called the 3 sisters. Each plant gives good energy to the other. Try it. You will be blown away by the quality of your veg.

How long can a one sweet corn plant produce for? We have just harvest corn from the plants, are they now useless and need to be replaced?

Yes, they need to be replaced as they will not crop again. They will die off. All the best, Bob

I have had an excellent first crop of sweet corn harvested in December. Each plant gave me one good corn kernel, even though two and sometimes three cobs were growing. Can you harvest two or three good corn cobs per plant or is it a myth? If so what is the secret?

It depends on the variety, some are far more productive than others. This year I grew Immali corn, it was pink/purple and white sweet corn. I got 3 cobs per plant.
