Yea, 40 is about the max for that space, maybe a few less is better. Trimming suckers is one of those topics people can discuss forever, but my opinion is leave them alone. Suckers often tastle, which is helpful in smaller plantings for pollination. Sometimes you even get some good ears on the bigger suckers.

Don't forget to side dress with a nitrogen rich fertilizer once or twice as the corn grows.

Thanks! I'll plan on thinning to under 40 per box.

I'll leave the suckers alone.

I wasn't planning to fertilize, but I guess I will on your advice. Probably I will just add compost.

Thanks again!
