Ambrosia isn't just a name, it's the perfect description for this white and yellow checkered sugar-enhanced sweet corn. The 8" long ears on 6 1/2' tall plants are plump, sweet and ready for summer picnics. SE.
When corn seedlings are 3-5" tall and healthy, thin to 1-foot apart. Give plants 1-2" of water every week. Suckers tend to form at the base of the plants; they help support the stalks and make food for the plant. The stalks may have to be staked in windy areas, but in general they are self-supporting.
Ears of corn are ready to harvest about 17-20 days after the silks appear. The corn kernels should be firm and milky when cut open. Firmly grip the ear and twist downward to harvest. Take care not to break the plant as harvesting the first ear or the second ear (when present) will not develop.
