Expected emergence is 7-10 Days; the listed maturity or bloom timing is 80-89 Days.

Silver King Sweet Corn seed is a standout selection for gardeners seeking a robust and flavorful harvest.
Saving seed
Seed saving for Silver King Because this product is a hybrid, saved seed will not be expected to reproduce the named commercial combination uniformly. 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
Silver King 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.
