Tomayto808, on corn (sweet & field) I only put one kernel to the hole. It will get crowded with three. Be careful removing the extra as you can damage or destroy the other.

It depends on how many holes in the container. 2 plants per hole is OK as long as the holes are at least 12 to 14 inches apart in all directions.

Sorry, I don't know anything about those containers... guess I should have read it better. I am speaking of planting in a row in a field. Thanks Shirley.

Hmmm...I didn't plant them that far apart. It's more like 8" in any direction. I used three 31gal containers and planted them 4 x 5. Too tight, huh? What's the downside? Smaller ears? That sucks.

Thanks for the feedback!

I'm using a raised bed, not an earthbox, but I planted 3 inches apart in 8 inch rows. So far so good, other than a raccoon that wanted a closer look at the middle!

Of course so far it's an experiment based on the advice of someone here that did it in a field.
