Seedling
2-3 weeksTiny plants with 2-4 true leaves, delicate and tender. Cotyledons are narrow and slightly reddish.
Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing early. Protect from strong winds and excessive heat stress.
Vegetative
4-6 weeksRapid growth phase with increasingly large, broad leaves on elongating stems. Plant develops deep red or bronze coloration in leaves and stems.
Ensure consistent moisture and apply balanced fertilizer every 3-4 weeks. Stake taller varieties if in windy locations. Pinch early buds if harvesting leaves primarily.
Flowering & Seed Head Formation
3-4 weeksTerminal seed heads emerge, initially green then gradually turning golden-bronze. Tiny flowers mature into seed clusters along the inflorescence.
Reduce nitrogen fertilizer to encourage seed development over foliage. Continue watering but allow soil to dry slightly between waterings. Support heavy flower heads with stakes if needed.
Seed Maturation
2-3 weeksSeed heads fully develop their characteristic golden color and become heavy and fully mature. Seeds at this stage are plump and ready for harvest.
Minimize watering to allow seeds to dry fully on plant. Watch for birds attempting to feed on ripening seeds; use netting if necessary. Allow some seeds to self-sow for next season if desired.
Harvest & Dry Down
At harvestSeed heads are fully mature, golden, and seeds separate easily from the head. Foliage may begin to yellow as the plant focuses energy on seed production.
Harvest seed heads as they mature to prevent shattering losses. Dry harvested heads indoors on screens for several weeks. Store dried seeds in cool, dry conditions.

Harvest Tips
For grain: Allow seed heads to fully mature and turn golden, typically 90-100 days after planting. Cut entire seed heads and dry indoors on screens for 3-4 weeks, then thresh by rubbing heads between hands over a cloth to separate seeds. For leaves: Harvest tender young leaves starting 4-6 weeks after planting by pinching off top 4-6 inches; regrowth occurs readily. Leaves are best when under 12 inches tall and tender.
