Hi, I live in adelaide and I am planning to plant corn as part of my school project however I was wondering whether it could be planted in May eventhough its not a best season for it. Will it still germinate and grow?

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?
