Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge 7-14 days after planting with minimal cotyledons. Foliage begins showing golden tones early.

Keep soil consistently moist but not waterlogged. Thin to proper spacing early to prevent competition. Protect from direct afternoon sun if germinating in extreme heat.

2

Vegetative Growth

4-6 weeks

Rapid growth phase with increasingly golden foliage and thick, sturdy stems. Plant reaches 3-4 feet tall with dense branching.

No fertilizer needed if soil is moderately fertile; excess nitrogen reduces seed production. Water during dry periods. Stake taller plants if in windy locations.

3

Flowering and Head Development

3-4 weeks

Terminal seed head emerges, initially green then transitioning to stunning deep red/burgundy color. Golden foliage provides striking contrast.

Reduce watering to encourage seed production over leaf growth. Monitor for pests. The red coloration intensifies as seed matures.

4

Grain Maturation

2-3 weeks

Seed head fully colored in deep red, seeds plump and mature. Lower leaves may yellow and drop. Seed detaches easily when rubbed.

Stop watering except in extreme drought. Harvest when seed head fully colored and seeds drop easily from panicle. Can cure on plant for several weeks.

5

Harvest and Drying

1-2 weeks for curing after harvest

Fully mature plants with all seed ready for collection. Seed heads may attract birds.

Cut heads and dry indoors in warm, well-ventilated area. Thresh to remove seeds. Store in cool, dry location.

Harvest Tips

Harvest entire seed head when it has fully turned deep red/burgundy and seeds drop easily when rubbed between fingers (typically 90-120 days after planting). Cut heads with 6-12 inches of stem and hang upside down in warm, dry area to cure for 2-3 weeks. Once fully dry, rub heads over paper or cloth to collect seeds. Store seeds in airtight container in cool location. For leaf greens, harvest young tender leaves anytime after plants reach 12 inches tall.
