Seeds germinate in warm soil (60°F+) and emerge as a single shoot with cotyledons. First true leaves appear within 7-10 days.

Ensure soil temperature is at least 60°F before planting; ideally 65-70°F for faster germination. Keep soil consistently moist but not waterlogged. Thin seedlings if direct sown too thickly.

Plant develops 4-6 true leaves and roots establish deeply. Height increases rapidly; secondary leaf development continues. Plant reaches 12-24 inches tall.

Apply nitrogen fertilizer once plants are 6 inches tall or at the 4-6 leaf stage. Keep weeds controlled through mulching or shallow cultivation (avoid deep hoeing that damages roots). Support plants with staking in windy areas if needed.

Tassels (male flowers) emerge from the top of the plant; ear shoots appear on lower nodes with silk strands emerging from the husk. Plant reaches full height (5-7 feet for standard varieties).

Increase water to 1.5-2 inches per week during this critical stage. Apply side-dressing of nitrogen fertilizer. Ensure consistent moisture for proper kernel development. Pollination occurs when pollen from tassels falls on silks.

Kernels fill with milk (liquid endosperm) and begin sizing. Silks darken and dry from tip downward. Ears feel full and plump.

Maintain even watering (1-2 inches weekly) to prevent stress and kernel shrinkage. Watch for pest damage and disease. Ears are vulnerable to animal predation—consider fencing or netting if needed.

Kernels reach full plumpness and maximum sweetness. Silks are mostly brown and dried. Ears feel tight in the husk; kernels yield milky liquid when punctured, progressing to doughy texture.

Harvest when kernels are in the milk to early dough stage for peak sweetness. Pick ears in the early morning for best flavor. Ears deteriorate quickly in flavor after peak ripeness—harvest every 2-3 days as ears mature.
