Depends why it is bad to grow it with it. Some anti companion plants attract the same bugs while others emit natural chemicals that hinder each other, some cross pollinate or need different conditions from one another. I do not know why Celery should not be planted with corn but 10meters should be plenty Have you tried an Aztec plot when growing corn? 3 crops from same patch. 16 corn 3 squash, zucchini or pumpkin and 1 bean growing up each corn plant (for nitrogen) per meter square. - Ferran

Aztec plot - sounds interesting! How do I find out more detail on how to plant one? Googled, but not much comes up. Thanks!

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!
