I'm tring to grow Temptaion variety corn this year. The stalks are maybe 1
to 1.5 ft. tall and half of them are flopping over. I've tried to mound
dirt around the base and prop them up but it doesn't seem adequate. I
have them growing in 2 stalks per place, rows a foot apart and plants 8
inches apart.

Did I not plant the seed deeply enough?

Not relevent.

Is having two together a cause?

It could be a factor (especially in making it harder to hill them up).
But too much nitrogen vs. potassium might also be a factor. Corn is
a grass, and needs plenty of nitrogen, but for strong stalks and disease
resistance it also needs potassium.

The weatheris also an important factor. One violent storm can wreck
havoc.

There's also a possibility of stalk rot. And heavy infestations of corn
root worm make the plants more likely to lodge (fall over).


Should I just pull them and start with new seed considering the season is
still young? Maturity is stated as about 60 days.

I'd pull to one plant per spot and, if the plants you pull look healthy (other
than the leaning over) try hilling them up again. You can be pretty
aggressive with the hilling up.

I sometimes use compost to hill up the corn if a bad storm knocks some
down. (Later in the season, I might use posts and run string to hold them
up.)
