Why is my corn falling over?

In my garden I have these two rows of sweet corn that I'm growing. Now it's been nearly two weeks since I planted my corn and it looks to be in the V2 stage but I don't know cause I'm a beginner gardener. I went to check my corn plants yesterday and noticed that a few corn plants were laying down beside where they were planted. They still had a root connected in the ground but looked like a bird or very small animal dug it up. I've looked online and saw that it could be that I didn't plant deep enough. I'm sure I planted it at least an inch deep but then I also saw online I was supposed to plant it 1 and a half to 2 and a half inches deep. I checked my other corn plants and they are nice and sturdy in the ground, and there were some that were about to fall over and I placed a little dirt around it and packed it softly so it would hold it upright. Now my question is, what is causing them to fall over with the one root still intact? If it's because of seed depth, can I place dirt around it and pack it a little or should I restart while I can and plant them deeper? One more question. If I can see a purple pink color near the base of the plant, does that mean I planted too shallow? Thanks for the help🙂👍

Howdy Dylan, May I give it a shot?  I always plant my corn in a block of rows. I hoe deep furrows in the garden and plant the seeds in the bottom of this. As the corn grows I slowly pull the soil from the top of the hills, that are along those furrows, and place it all along the row at the base of the corn stalks. So as the corn grows the soil is getting deeper over the roots and I end up with the corn looking like it is at the top of the hill with a deep furrow between the rows that I use for irrigation and mulching. Does that make sense?

I plant in a block so that the corn around the outside acts as sort of a wind break for those inside the block, and I think that it helps with pollination.

So I am not sure why your corn is falling. Do you get much wind? Does it look like animals might be knocking them down?  Putting soil around the bases of the stalks as you stand them up again would be what I would try. Unless they look like they have died, then you might have to replant.  Then you might have to put up a fence to keep animals out?

I've had years when crows would come and pull out the seedlings to get at the underground seed.  They are very smart and challenging to battle!
