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 help๐๐
