Cdog, I think the secret to growing corn is giving it plenty to eat. I fertilize the ground when I plant, and then when the corn is about one foot or so in height, I will side-dress with another application of fertilizer and work it into the soil. I till between the rows a couple of times during the season and I hoe the grass and weeds from around the corn once. I hill the corn once, and that's about all I do to it.
I think some varieties of corn are easier to have success than others, too. SH2 corn is more picky on the planting temps than SH corn, for example. I grow SH2 corn, so I have to wait until the ground is good and warm, and the weather forcast calls for warm temps for the coming week or so.
This year has been a good year for corn. I have some stalks with 3 ears on them, and that's never happened to me before!! Don't give up!!
