From sowing to harvest, a corn seed takes 55 to 95 days to grow, depending on what type of corn is planted as well as the climate it is grown in. The time from planting corn seed to germination is normally about 5 to 12 days.
Corn requires more water than many other vegetables. The ground should be kept moist at all times, but the tassels must stay dry. The pollen from the tassels falls on the corn silk, making kernels. Planting corn in blocks rather than rows makes tasseling easier. Corn has a very shallow root system and needs extra stalk support that can be provided by building mounds of earth around the bottom of each stalk.
