Sweet Corn – 1,700-3,500 seeds/lb (2,500 avg)

Corn (Zea mays) is a warm season tender annual in the Gramineae family, which contains almost all of the grains and grasses. Corn varieties have been specialized for many uses including sweet corn, popcorn, and flint corn, which is milled into cornmeal.

Soil Nutrients and Requirements

Corn requires high fertility and deep, well drained fertile soils with a pH between 6.0-6.8. Corn can tolerate heavy soils. Corn is a heavy feeder, fertilize ground well in spring with high-quality compost or a complete fertilizer. For specific nutrient needs and application rate it is always best to have a soil test done before application. Side dress with fertilizer at 12”, or when leaves start yellowing.
Sweet corn seeds are susceptible to rotting in cool, wet conditions because their sugars are attractive to fungi and they’re growing more slowly.

Seeding Depth

Seeding depth: 1-2”

Plant Spacing

For early varieties 8-10” ”; for main season crops 10-12”

Row Spacing

Row Spacing: for early varieties 24″; for main season crops 30-36”. Plant each variety in blocks of at least 4 rows for adequate pollination.

When to Sow

Direct seed only after soil has warmed to 65°F, after all danger of frost has passed, to ensure germination. Optimal soil temperature for germination is 85°F. Corn can also be transplanted, which is becoming more common in regions with shorter growing seasons.  Start transplants in small cells 3-4 weeks before planting date. Double up plants per cell to save space and increase final plant spacing to accommodate.

Other Considerations

To avoid cross pollination, separate blocks of individual varieties by at least 500 ft or plant to ensure tasseling at different times (plant varieties with different days to maturity, or use successive planting dates). Plants are in pollination mode for 2 – 3 weeks from time of tassel. If planting successions of the same variety, wait until the first succession reaches 2” before planting the next. This can be continued until 80 days before expected frost.  Successive plantings of different varieties (to avoid cross pollination) should be made at 8 leaf stage of last planting.

Harvest

Harvest when ear silks have dried down and when kernels are filled to the tip and have colored up. Corn is generally ready 18-24 days after first silk has formed

Storage

For best quality, eat right away. Cool corn to 32°F within one hour of harvest. Corn will hold well for 1-4 days at 32°F and high humidity, but will decrease in sugars more rapidly at higher temps and longer duration.
