Hi Phoebe. If you plant corn outside now it might germinate if you are lucky, but it won't grow much because it is too cold. Best time to plant it is in spring or early summer. You might like to try peas or broad beans for this time of the year. Both are easy to germinate and grow. If you are looking for a grassy type of plant to grow, try wheat or barley. Good luck.

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.

you can use the stalks to grow your peas up.

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.

Hi Got about 8-10 stalks of black chewey corn - been flowering for last week and have a few tassels also , however I was trying to manually pollinate them but when shake the flowers over a white pot don't seem to be any pollen just the small flower pieces fall off and lots lots small ants , also plants covered in small ants ? - some plants also have leaves dried up and crispy looking , they get watered daily had also plenty rain recently and they have been fed with organic pellets as well as compost . They also covered in mulch and have peanuts surrounding them .. Why no pollen and what to do if anything about the ants ? Thanks
