Old Fashioned Sweet Corn - Key Growing Information
SCIENTIFIC NAME: Zea mays
CULTURE: Corn varieties which reproduce true to type from seeds year after year are referred to as "open-pollinated (OP)" or "standard." These varieties do not have the uniformity or tenderness of today's hybrids. While many people enjoy their old-fashioned chewiness and taste, we suggest using OP's on a small scale if you're unfamiliar with them. Sow 3/4-1" deep, 6-7" apart (or 2 seeds every 9", thinning to 1 plant), rows 30-36" apart. Increase this rate for untreated seeds. Arrange in blocks of at least 4 rows for proper pollination, which is needed for well-filled ears. Successive plantings can be made through early summer; most growers prefer to extend the sweet corn season by planting a few varieties of different maturities.
INSECT PESTS: Consult your local Extension office for Integrated Pest Management information. Reduce insect pests in the next corn crop by prompt plowing-in or removal and composting of cornstalks after harvest.
HARVEST: When kernels are full and "milky," generally indicated by a drying and browning of the ear silks. Record the date on which about half the plants show silk. Corn is ready to eat 18-24 days after ear silks first show; the warmer the weather, the sooner you can pick it.
DAYS TO MATURITY: Varies widely with weather conditions and planting dates. Use these figures to compare one variety to another, not to accurately predict maturity on a given day.
