Seedling
10-14 daysSingle leaf emerges; plant is 2-4 inches tall with developing root system
Keep soil consistently moist; protect from birds and cutworms with row covers if needed; thin to proper spacing when 3-4 inches tall
Vegetative Growth
4-5 weeksPlant develops 6-12 leaves; height increases to 12-24 inches; strong root system establishes
Maintain consistent moisture; side-dress with nitrogen fertilizer when plant reaches 12 inches; remove weeds and provide weed control; stake if in windy location
Flowering & Tasseling
2-3 weeksTassel emerges at top; silks appear on ears; plant reaches 6-8 feet tall; pollen is produced
Ensure adequate water during this critical stage; avoid nitrogen excess which delays pollination; hand-pollinate or allow wind pollination; keep area free of competition
Ear Development & Pollination
3-4 weeksSilks receive pollen; kernels begin filling; ears swell with developing kernels; husks protect forming corn
Maintain consistent deep watering; provide 1.5 inches per week if no rain; monitor for pests; avoid disturbing plants during this sensitive period
Maturity & Drying
2-3 weeksKernels harden and develop deep blue-purple color; husks dry and pull back slightly; kernels dent slightly at top when fully mature
Reduce watering once silks brown completely; allow ears to dry on stalk in field if weather permits; harvest when kernel reaches full color and dent stage

Common Pests
-
Monitor for egg clusters on leaves; remove infested plant parts; use Bt (Bacillus thuringiensis) spray; plant trap crops; maintain good sanitation
-
Apply mineral oil to silk tips after pollination; use Bt spray; handpick infected ears; encourage parasitic wasps
-
Use row covers on young plants; apply Bt spray; handpick larvae; encourage beneficial insects; remove affected foliage
-
Hand-pick beetles in early morning; use neem oil; set beetle traps away from corn; encourage natural predators
-
Remove infected galls before they burst; avoid overhead watering; improve air circulation; practice crop rotation
-
Use netting or scare devices; plant in blocks to reduce edge predation; allow some volunteer corn as trap crop

Harvest Tips
Harvest when kernels reach full blue-purple color and show slight denting at the top; this typically occurs 20-25 days after silking; snap ear downward and away from stalk; husk immediately and air dry for 6-8 weeks before grinding or storage; for popcorn, allow kernels to dry completely until extremely hard (moisture content below 12%)
