>>1073816For sweet corn, you pick it before it dries so you can eat it on the cob. For flint and dent corn you let it dry on the stalk then harvest it. Corn likes lots of nitrogen so side dressing it with compost or watering with compost tea or manure tea should be done. There's not much maintenance needed if you keep weeds down. You can use the 3-sisters method to help with weeds and get more out of the land. The biggest mistake people make is planting it too spaced out. They are wind pollinated and need to be close enough to each other to dust the silks with pollen from the tassels. The biggest problem I have is with storms knocking the corn over and raccoons raiding everything. So, I use electric fencing and grow short varieties.
