Seedling
2-3 weeksTiny seedlings emerge with small oval cotyledons and develop 2-4 true leaves within 1-2 weeks.
Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing early. Protect from strong winds and pests.
Vegetative Growth
4-6 weeksPlant develops broad, elongated leaves along a central stem, growing rapidly in warm weather. Height increases significantly (3-6 feet depending on variety).
Provide consistent moisture and warmth. Fertilize every 3-4 weeks with balanced fertilizer. Pinch tops for bushier growth if desired. Harvest outer leaves for greens if desired.
Flowering & Seed Head Formation
3-4 weeksTerminal flower head emerges at the top of the plant, initially compact and erect, then elongates. Golden seed head develops distinctive drooping or plume-like structure.
Reduce nitrogen fertilizer to encourage seed development over leaf growth. Monitor for pests. Continue moderate watering.
Seed Maturation
3-4 weeksSeed head becomes fully formed and heavily laden with developing seeds. Color deepens to golden-yellow, and stems may develop a reddish tint.
Reduce watering frequency. Support tall plants with stakes if needed in windy areas. Watch for birds attempting to feed on ripening seeds.
Harvest & Drying
1-2 weeks dryingSeeds fully mature and head dries. Seeds are readily shed when rubbed between fingers, indicating harvest readiness.
Cut seed heads when 80-90% of seeds are dry. Hang upside down to cure for 1-2 weeks. Thresh and clean seeds before storage.

Harvest Tips
For grain: harvest when seed heads are fully mature and seeds fall easily from the head (late summer/early fall). Cut the entire head, hang upside down to dry completely in a warm, airy location for 1-2 weeks, then thresh by hand or foot to separate seeds from chaff. For greens: harvest outer leaves once plant is 6-8 inches tall, pinching gently to encourage bushiness. Store dried seeds in an airtight container in a cool, dry place for up to 2 years.
