Starting Double Red from seed
How to grow Double Red Sweet corn
Botanical identity: Zea mays L. Life cycle: Annual.
Sow 1 in and use a seed-zone temperature near 70–85 °F. Expected emergence: 7-10 Days. Direct sow after frost when the seed zone is warm; do not soak seed in cold or waterlogged soil
Plant during Late Spring. Space plants 8 in apart with 30 in between rows or planting bands.
Provide Full sun, moderate water, and loamy near pH 6.0–6.5. Support: No-Support.
Garden performance and care
Plant Double Red in a block rather than one long row so wind-carried pollen reaches the silks. Keep the bed evenly watered from tasseling through ear fill, and protect mature ears from birds and mammals if seed saving. Expected emergence is 7-10 Days; the listed maturity or bloom timing is 80-89 Days.
Harvest, bloom, and uses
Double Red is best for block planting, dependable pollination, dry or fresh harvest, and seed saving. Harvest form or size: Varies with the maintained seed lot and growing conditions. Color at the principal harvest or mature stage: Red. Double Red Sweet Corn seeds produce a striking heirloom corn with richly colored stalks, ornamental beauty, and sweet, tender ears that bring unusual color and historic character to the garden.
Saving seed
Seed saving for Double Red Select several healthy, true-to-type plants so the saved lot represents the variety rather than one unusually early or large individual. Corn is wind-pollinated and highly outcrossing. Grow a substantial population in a block rather than one long row, and isolate the seed crop from other corn by distance, flowering time, or controlled pollination. Mark representative plants before pollen shed and remove clear off-types before they contribute pollen. For seed, leave ears until husks are brown and kernels are hard. Harvest before prolonged wet weather or animal loss, remove husks, and dry ears with strong air circulation until kernels cannot be dented with a fingernail. Shell, screen, and winnow only after full dry-down. Label the crop, cultivar, lot, year, field, population size, isolation method, selected plants, and any unusual ears. Store fully dry seed cool, dark, and protected from moisture and rodents. Test germination before an important planting.
Common problems
Double Red can be affected by poor pollination, corn earworm, armyworms, stalk lodging, smut, leaf diseases, birds, and rodents. Plant in a block, maintain even moisture at tasseling and silking, use balanced fertility, rotate crops, and inspect ears before storage. Uneven kernel fill usually points to pollen or silk stress rather than a seed-count problem.
