About Early Xtra Sweet Sweet Corn: Though historical records differ, it seems that the first sweet corn was obtained at the beginning of the 19th century; the Indians provided early settlers of the northeastern United States with this valuable commodity. In 1825, Thorburn's seed catalog offered the first cultivated variety of sweet corn for sale.
Early Xtra Sweet Sweet Corn Germination: Prepare the soil with compost or other organic matter. One week after frost or when the soil consistently reaches 60 degrees F, plant the corn 1" deep and 8-12" apart. Planting blocks of four short rows ensures good pollination. Germination should take place in 5-6 days. For companion planting benefits, plant corn with cucumbers, peas, or pole beans; plants that like shade also do well with corn. Avoid planting tomatoes near corn.
Growing Early Xtra Sweet Sweet Corn Seeds: After the corn emerges, keep it moist and carefully remove weeds; since corn cannot fight against weeds, mulch may be beneficial. Additional organic matter or compost helps growth, since corn is a heavy feeder. Keep in mind that corn has shallow roots which can easily become damaged by hoeing. Watch out for pests, as corn attracts many problematic insects and animals.
Harvesting Early Xtra Sweet Sweet Corn: About three weeks after the corn silk appears, it will begin to turn brown; this signals that the corn is nearly ripe. When the kernels of sweet corn release a milky substance when pierced, they are ready to be harvested. If the substance is clear, they are not ready; if nothing comes out of the kernel, the optimum time for harvest has passed. Sweet corn usually tastes sweetest if picked in the morning, since sugar content peaks at this time; for best taste, use it the same day it is picked.
Saving Early Xtra Sweet Sweet Corn Seeds: Because this variety of corn is a hybrid, the seed it produces will either be sterile or will revert to the characteristics to one of the parent seeds; reproducing this type from its own seed will not be successful.
