Corn is a warm weather crop and should not be planted until the soil warms up to 60° F. It is one of the taller home garden crops, so locate it where it will not shade out other crops. Plant in full sun, in fertile, well-drained soil. Several rules apply to insure an adequate corn crop: 1. Corn is wind pollinated, and to insure adequate pollination, sow seeds in several rows to form a square, or on hills with several plants in a circle. A minimum of 12 or more plants is usually necessary. Do not plant in one long row. 2. Corn is a heavy feeder and must have ample nitrogen and water at all times, but water the soil, not the plant or pollination could suffer. 3. Corn roots do not tolerate disturbance well, so when thinning corn, cut the excess sprouts instead of pulling them. Do the same with nearby weeds and after corn is established mulch to reduce weeds rather than cultivating around their roots and damaging them. 4. Some sweet corns can be adversely affected by cross pollination from other corn varieties, so follow cultivar label directions precisely to avoid pollen contamination from other corn. 5. Time of harvest is important for some sweet corns, so follow harvest directions carefully for the particular variety you are growing. Hard corns need to dry on the stalk, so harvest time is not a particular issue for them. |
