try gently tapping the corn stalks with a broom handle in the middle of the day to allow pollen to drop over the plant.. i do this everyday while the corn is flowering and i get excellent results

Hi, I planted corn 4 weeks ago. They are now seedlings, but all these ants have taken up to living inside them. Also, there is a jumping, ant sized insect in there as well. I am worried that the insect will eat the flowers. Any info/ideas?

Would someone please advise if I should cut the top out of my corn? It is over 6 feet tall and I am worried the growth is going in height and not into the cobs? I live in Tassie and have had a hot summer for us this year. I have mulched in sugar cane and the corn has thrived from this...

Don't cut the tops off. That's the male part of the plant and drops pollen usually before the female silks on the same plant are ready. Most of the growth in corn occurs before the male part springs out and cutting it off doesn't help.

My husband has grown corn for the first time this year. He planted seedlings from a giant hardware chain. I don't know the variety. The stalks are short but the corn cobs are full and beautiful and not too dry or flowery - perfect except they're not very 'sweet'. Are we being impatient & it needs more time? Or is this a lack of heat, nutrient or something else? Thanks!
