Try Hopi Turquoise to make blue flour, Japanese Hulless for popcorn and Inca Rainbow for beautiful ears of rare sweet corn. Remember to stagger the planting dates so the corn isn't tasseling during the same two weeks. When different varieties cross pollinate, one ruins the taste of the other. Supersweet corn, for instance, becomes tough when pollinated by standard corn. What to do Once you find enough space for the blocks, corn is a fairly easy crop.
Corn needs full sun and rich soil.
Dig compost to a depth of eight inches. Use a hoe to pull soil 3 or 4 inches high to make raised planting mounds. The mounds should be 24 to 36 inches apart. Sow seeds 12 inches apart and cover with one to two inches of soil. The furrows in between rows are for irrigation.
